Updated: 2026-08-05

Overview

The 74LCX162374 is a 16-bit edge-triggered D-type flip-flop with 3-state outputs, designed for low-voltage digital systems. It operates within a voltage range of 2.0V to 3.6V, making it ideal for battery-powered and energy-efficient applications. This IC is part of the 74LCX family, known for its high-speed performance and low power consumption. It is commonly used in embedded systems, networking hardware, and communication devices where reliable data storage and transfer are critical. The 74LCX162374 features bus-hold on data inputs, which eliminates the need for external pull-up or pull-down resistors, simplifying circuit design. Its 3-state outputs allow multiple devices to share a common bus, enhancing system flexibility. The IC is available in various package types, including TSSOP and SOIC, catering to different PCB layout requirements.

Structure and Working Principle

The 74LCX162374 consists of 16 individual D-type flip-flops, each with a data input (D), clock input (CLK), and output enable (OE) control. The flip-flops capture data on the rising edge of the clock signal and present it at the outputs when OE is active. When OE is inactive, the outputs enter a high-impedance state, allowing other devices to drive the bus. Internally, the IC uses CMOS technology, which ensures low power dissipation and high noise immunity. The bus-hold circuitry maintains the logic state of unused inputs, preventing floating conditions. This design minimizes power consumption and improves signal integrity in high-speed applications. The 74LCX162374 also features balanced propagation delays, ensuring synchronized data transfer across all bits.

Key Features

The 74LCX162374 offers several key features that make it suitable for modern digital systems. Its low-voltage operation (2.0V to 3.6V) reduces power consumption, extending battery life in portable devices. The 3-state outputs enable bus sharing, simplifying multi-device communication. The bus-hold function on data inputs eliminates the need for external resistors, reducing component count and board space. Additionally, the IC supports high-speed operation, with typical propagation delays of less than 5 ns. It is compatible with 5V-tolerant inputs, allowing seamless integration with legacy systems. The 74LCX162374 is also designed for robust performance, with ESD protection exceeding 2000V, ensuring reliability in harsh environments. These features make it a versatile choice for industrial, automotive, and consumer electronics applications.

Application Areas

The 74LCX162374 is widely used in applications requiring reliable data storage and transfer. In embedded systems, it serves as a buffer or latch for microprocessors and FPGAs. Networking equipment, such as routers and switches, utilizes this IC for data routing and signal conditioning. Communication devices, including smartphones and tablets, employ it for interfacing between subsystems. Industrial automation systems benefit from the 74LCX162374's low-power operation and high noise immunity, ensuring stable performance in noisy environments. Automotive electronics, such as infotainment systems and engine control units, also leverage its robustness. The IC's versatility and reliability make it a staple in B2B procurement for electronics manufacturers and design engineers.

Maintenance and Precautions

To ensure optimal performance of the 74LCX162374, follow these maintenance and precautionary measures. Avoid exposing the IC to static electricity by using grounded workstations and anti-static packaging. Adhere to the recommended voltage levels (2.0V to 3.6V) to prevent damage or unreliable operation. Ensure proper heat dissipation in high-speed applications to avoid thermal stress. When designing PCB layouts, minimize trace lengths to reduce signal degradation. Use decoupling capacitors near the power pins to stabilize the supply voltage. Regularly inspect solder joints for cracks or cold solder, especially in vibration-prone environments. By following these guidelines, the 74LCX162374 can deliver long-term reliability in demanding applications.

B2B Procurement Guide

When procuring the 74LCX162374 in bulk for B2B purposes, consider the following factors. Verify the supplier's authenticity and certifications to avoid counterfeit components. Check for industrial-grade or automotive-grade variants if the application requires extended temperature ranges or higher reliability. Compare prices across multiple vendors, keeping in mind that volume discounts may apply. Evaluate lead times to ensure timely delivery, especially for large orders. Request samples for testing before committing to a bulk purchase. Confirm packaging options, such as tape-and-reel for automated assembly. Additionally, review the supplier's technical support and return policies. These steps will help secure high-quality components at competitive prices, ensuring smooth production workflows.
