CD74HCT354E

Signal Switches, Multiplexers, Decoders Overview

The CD74HCT354E is an 8-line to 1-line multiplexer from the HCT series, manufactured by Harris Corporation. It features transparent address latches and registered data inputs within a single functional unit. The device operates on a 4.5V to 5.5V supply voltage and utilizes CMOS technology with complementary outputs. It is housed in a 20-pin Dual In-Line Package (PDIP) and supports a wide operating temperature range from -40°C to 85°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify component authenticity through manufacturer documentation or authorized distributors. Confirm package integrity and pin alignment against the 20-PDIP specification. Ensure compliance with project requirements regarding RoHS status, as indicated in available records. Validate operating temperature ranges match environmental constraints before integration.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when HCT logic compatibility with 5V systems is required alongside multiplexing functionality. The registered data input feature distinguishes it from standard multiplexers lacking internal latching. Consider the PDIP package for prototyping or applications requiring through-hole mounting capabilities.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the CD74HCTxxxyy family of high-speed CMOS logic devices produced by Harris Corporation. The series is designed to provide performance comparable to LSTTL while offering significant power reduction. The specific model integrates multiplexer functions with latch capabilities, serving specialized data handling roles within broader logic families.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Cross-reference with CD74HC354 variants if HC speed characteristics are acceptable instead of HCT. Verify pinout compatibility with existing PCB layouts when substituting.
