CD74HC354E

Overview

The CD74HC354E is an 8-line to 1-line multiplexer belonging to the HC series of high-speed CMOS logic devices. Manufactured by Harris Corporation, this integrated circuit features a single functional unit with eight data inputs and one primary output, complemented by a complementary output pin. It operates within a supply voltage range of 2V to 6V and supports a maximum frequency of 38MHz. The device utilizes a 16-pin Dual In-Line Package (DIP) suitable for through-hole mounting. It functions reliably across an extended industrial temperature range from -55°C to 125°C.

Feature Summary

• Provides transparent address latching capabilities for registered data input handling.
• Features three-state outputs allowing direct connection to bus structures.
• Supports bidirectional transmission control for multiplexed data applications.

Applications

• Data routing in digital communication systems
• Address decoding circuits
• Multiplexed signal transmission

Procurement Notes

Verify component authenticity as original Harris manufacturing records may be archived. Confirm package integrity and pin alignment against standard DIP-16 specifications. Check datasheet revisions for electrical parameter updates. Ensure environmental compliance status matches project requirements given historical RoHS non-compliance indicators. Validate supplier documentation for traceability.

Selection Notes

Select this component when an 8-to-1 multiplexer with registered inputs and three-state outputs is required. The HC series offers compatibility with standard TTL logic levels while maintaining low power consumption. Consider the wide operating temperature range for harsh environments. Verify that the DIP-16 package fits the target PCB layout constraints.

Part Context

This part belongs to the Harris CD74HCxx series of high-speed CMOS logic components. These devices were designed to provide performance comparable to the older 74LS series but with lower power dissipation. The specific model integrates multiplexing functionality with latch registers, distinguishing it from standard combinational logic gates within the same family.

Replacement Considerations

Cross-reference with other manufacturers' 74HC354 equivalents. Verify pinout compatibility before substitution. Ensure voltage and current ratings meet system specifications. Check for any functional differences in latch behavior or output drive strength.
