74AC377MTCX

Overview

The Fairchild Semiconductor 74AC377MTCX is an octal D-type flip-flop featuring clock enable functionality. It utilizes advanced silicon-gate CMOS technology to provide high-speed operation with low power consumption. The device includes eight separate D-type inputs and outputs, controlled by a common buffered Clock (CP) and Output Enable (OE). It offers true outputs and is housed in a 20-lead TSSOP package.

Feature Summary

• Octal D-type flip-flop architecture with clock enable control
• Buffered positive edge-triggered clock input for signal integrity
• High noise immunity and low power consumption characteristics
• Capable of driving standard TTL loads

Applications

• Bus-oriented data storage systems
• Register applications requiring clock enable gating
• Parallel-to-serial data conversion circuits
• General-purpose digital logic interfacing

Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor products are now managed under ON Semiconductor. Confirm that the component meets current environmental compliance standards such as RoHS. Ensure the package type matches the required PCB footprint and verify pin compatibility if replacing legacy components from other manufacturers.

Selection Notes

Select this component when an octal flip-flop with explicit clock enable capability is required, distinguishing it from transparent latch variants like the 74AC373. Consider the 20-lead TSSOP package for surface-mount assembly constraints. Evaluate the propagation delay and output drive strength against system timing requirements and load conditions.

Part Context

This part belongs to the 74AC logic family, which represents high-speed CMOS technology compatible with standard 74LS logic functions. The AC series provides improved switching speeds compared to earlier HC or HCT families while maintaining low static power dissipation. It is designed for applications demanding faster data processing rates.

Replacement Considerations

• MC74AC377MTCX
• SN74AC377N
• SN74AC377NSR
