CD54HCT257F3A

Signal Switches, Multiplexers, Decoders Overview

The CD54HCT257F3A is a military-grade quad 2-input multiplexer featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended temperature range from -55 °C to +125 °C. The device utilizes High-Speed CMOS logic technology and is housed in a 16-lead ceramic dual-in-line package (CDIP).

Signal Switches, Multiplexers, Decoders Feature Summary

Military-grade reliability with ceramic packaging for harsh environments.
Quad configuration providing four independent 2-input multiplexing channels.
Three-state outputs allowing direct bus interfacing with high-impedance control.

Signal Switches, Multiplexers, Decoders Applications

Data acquisition systems requiring multi-channel signal selection.
Military avionics and defense electronics operating under extreme temperatures.
High-speed data routing between registers and common output buses.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'F3A' to confirm the ceramic package and military qualification status. Ensure the design accommodates the through-hole mounting style required by the CDIP-16 form factor. Confirm that the 4.5 V to 5.5 V supply range aligns with the system power architecture before finalizing procurement specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when military-grade environmental resilience and wide temperature operation are mandatory. The HCT logic series ensures TTL-compatible input levels while maintaining CMOS low power consumption. Consider the CDIP-16 package constraints if space or board layout requires surface-mount alternatives.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the CD54xx family, which denotes military-grade specifications distinct from commercial CD74xx variants. It shares functional similarities with the CD54AC257 but offers different speed and power characteristics inherent to the HCT technology node.
