CD54HCT564F3A

Overview

The CD54HCT564F3A is a military-grade, high-speed CMOS logic device featuring octal D-type positive-edge triggered inverting flip-flops with three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to 125°C. Key electrical parameters include a maximum propagation delay of 44 ns at nominal voltage, a maximum frequency of 25 MHz, and output drive capabilities of 6 mA (IOL) and -6 mA (IOH). The component utilizes a 20-pin ceramic dual in-line package (CDIP) and draws a maximum quiescent current of 0.08 mA.

Feature Summary

Military-grade reliability for extended environmental operation
High-speed CMOS technology for efficient performance
Octal configuration with three-state output control

Applications

Military aerospace systems requiring robust logic components
High-speed data storage registers
Industrial control interfaces

Procurement Notes

Verify the specific suffix F3A against official Texas Instruments documentation to confirm packaging and material specifications. Ensure compatibility with existing military-grade supply chains and validate that the 20-CDIP package meets mechanical constraints. Confirm availability through authorized distributors as this part may have limited production runs.

Selection Notes

Select this component when military-grade temperature tolerance and high-speed digital storage are required. The HCT series ensures TTL-compatible input levels while maintaining CMOS low power consumption. Verify that the octal width and three-state functionality align with system bus requirements before finalizing the design.

Part Context

This device belongs to the Texas Instruments CD54HCT family, designed for high-performance digital applications. The '54' prefix indicates military-grade qualification, distinguishing it from commercial '54HC' variants. It serves as a specialized solution for environments demanding strict reliability standards alongside standard logic interface compatibility.

Replacement Considerations

SNJ54ALS564BJ offers similar octal flip-flop functionality but differs in speed and power characteristics. Verify pinout compatibility and electrical parameter alignment before substitution.
