SN74LS112N

Overview

The SN74LS112N is a dual J-K negative-edge-triggered flip-flop IC designed for digital electronics applications. Manufactured by Texas Instruments, it is part of the 74LS series, known for its reliability and cost-effectiveness. The IC features preset and clear inputs, making it versatile for various timing and data storage tasks. It operates within a voltage range of 4.75V to 5.25V, making it suitable for TTL (Transistor-Transistor Logic) systems. The SN74LS112N is widely used in industrial, automotive, and consumer electronics due to its high noise immunity and robust performance. Its compact DIP (Dual In-line Package) form factor allows for easy integration into circuit boards, making it a popular choice among engineers and designers.

Structure and Working Principle

The SN74LS112N consists of two independent J-K flip-flops, each with preset (PRE) and clear (CLR) inputs. These flip-flops are triggered on the negative edge of the clock pulse, ensuring precise timing and data synchronization. The J and K inputs determine the state of the flip-flop, while the clock input controls the timing of state changes. When the clock signal transitions from high to low (negative edge), the flip-flop captures the data present at the J and K inputs. The preset and clear inputs allow for immediate setting or resetting of the flip-flop, independent of the clock signal. This functionality makes the SN74LS112N highly flexible for various digital logic applications.

B2B Procurement Guide

When procuring the SN74LS112N in bulk for B2B purposes, it is important to consider several factors. Verify the supplier's credibility and ensure the components are sourced from reputable manufacturers like Texas Instruments. Check for certifications such as RoHS compliance to meet environmental and safety standards. Price negotiations should account for volume discounts, with reference prices typically ranging from $0.50 to $2.00 per unit. Lead times and minimum order quantities (MOQs) should also be clarified to align with production schedules. Additionally, consider the availability of technical support and datasheets from the supplier to facilitate seamless integration into your projects.
