74VHC112M

Overview

The Fairchild Semiconductor 74VHC112M is an octal D-type flip-flop with 3-state outputs, part of the advanced high-speed CMOS VHC series. It features a single clock input (CP) and eight D inputs controlling corresponding Q outputs. The device includes power-down protection on all inputs to minimize standby current. It operates within a supply voltage range of 2.0V to 5.5V and is housed in a 20-lead SOIC package.

Feature Summary

• Octal D-type flip-flop architecture with 3-state outputs for bus-oriented memory operations
• Advanced silicon-gate CMOS technology ensuring high noise immunity and low power dissipation
• Power-down protection provided on all inputs to prevent floating states during shutdown

Applications

• Bus-oriented memory register implementations
• 8-bit shift registers in digital logic circuits
• Parallel-to-serial data conversion modules

Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor has been integrated into onsemi. Confirm that the ordering code matches the exact suffix requirements for the SOIC-20 package. Ensure compliance with RoHS standards and check for any updated nomenclature changes due to corporate integration.

Selection Notes

Select this component when an 8-bit storage element with tri-state capability is required. It offers performance comparable to Bipolar Schottky TTL while maintaining CMOS power efficiency. Suitable for designs needing wide voltage operation from 2V to 5.5V and robust noise immunity in mixed-signal environments.

Part Context

This component belongs to the 74VHC family, which provides high-speed operation similar to equivalent Bipolar Schottky TTL logic. The VHC series is designed to maintain low power dissipation typical of CMOS technologies while offering improved switching speeds. It serves as a standard solution for general-purpose digital logic applications requiring octal storage.

Replacement Considerations

Check for equivalents such as the 74VHC374MX or other octal D-type flip-flops with 3-state outputs from compatible manufacturers. Verify pin compatibility and electrical specifications before substitution.
