74LCX112M

Overview

The Fairchild Semiconductor 74LCX112MTC is a dual JK negative edge-triggered flip-flop with set and clear inputs, housed in a 16-TSSOP package. It operates on a supply voltage range of 2V to 3.6V. The device features low input current and high noise immunity typical of the LCX series. It supports asynchronous set and clear functions independent of the clock signal. The component is designed for low-voltage applications requiring high-speed performance.

Procurement Notes

Verify the exact suffix (e.g., MTC vs MTCX) against the manufacturer's official datasheet to confirm packaging type, as suffixes indicate specific reel or tube configurations. Ensure the ordering code matches the required pinout and thermal specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm active status and availability. Do not assume functional equivalence between different suffix variants without explicit documentation.

Selection Notes

Select this component for designs requiring dual JK functionality in low-voltage systems. Consider the 16-TSSOP package for surface-mount assembly constraints. Verify that the operating voltage range aligns with the system's power supply. Check timing requirements against the datasheet parameters for propagation delay and setup/hold times. Ensure compatibility with existing logic levels if interfacing with higher voltage devices.

Part Context

The 74LCX112 belongs to the LCX family of low-voltage CMOS logic devices. This series is characterized by high speed and low power consumption. It is compatible with standard 5V logic interfaces despite lower operating voltages. The device serves as a fundamental building block for sequential logic circuits in modern electronic systems.
