CD54HC377F3A

Overview

The CD54HC377F3A is a high-speed CMOS logic octal D-type flip-flop with data enable, manufactured by Texas Instruments. It features eight independent D-type flip-flops with positive-edge triggering and an active-low clock enable input. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 23 MHz. Propagation delay is typically between 10 ns and 50 ns. It is rated for military operation across a temperature range of -55 °C to 125 °C. The component utilizes a 20-lead ceramic dual in-line package (CDIP) designed for high reliability in demanding environments.

Feature Summary

High-speed CMOS technology providing balanced outputs and fast propagation delays
Octal configuration with eight independent D-type flip-flops and positive-edge triggering
Active-low clock enable input for precise data synchronization control
Military-grade rating ensuring reliable performance across extreme temperature ranges

Applications

Military aerospace systems requiring high-reliability digital logic
Data storage registers in defense communication equipment
Shift register applications in harsh environment instrumentation
Industrial control systems operating under extreme thermal conditions

Procurement Notes

Verify the specific suffix F3A corresponds to the required 20-lead ceramic dual in-line package (CDIP) configuration. Confirm that the military temperature rating (-55 °C to 125 °C) aligns with system environmental specifications. Ensure compatibility with existing board layouts for through-hole mounting. Validate that the high-speed CMOS characteristics meet the timing requirements of the target application circuit.

Selection Notes

Select this component when military-grade reliability and wide temperature tolerance are mandatory. The HC series offers higher speed than standard TTL while maintaining CMOS low power consumption. The CDIP package provides superior mechanical stability compared to plastic variants. Consider the 2 V to 6 V supply range flexibility for various logic interface levels in complex systems.

Part Context

This part belongs to the Texas Instruments CD54HC377 family of octal D-type flip-flops. It shares functional similarities with the CD54HC377 but specifies the F3A suffix for the ceramic DIP package. The family includes related parts like the CD54HCT377 for TTL-compatible inputs. These components are designed for high-performance digital processing in critical applications.
