CD74HC4514EG4

Overview

The CD74HC4514EG4 is a high-speed CMOS logic device manufactured by Texas Instruments, belonging to the HC series. It functions as a 4-to-16 line decoder and demultiplexer with an integrated address latch. The component operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a DIP-24 package. It features four input lines and sixteen output lines, with a propagation delay of 23 ns. The device is rated for operation between -55°C and +125°C.

Feature Summary

• Integrates a 4-to-16 line decoder with a dedicated address latch for stable decoding operations.
• Utilizes advanced silicon-gate CMOS technology to provide high noise immunity and low power dissipation.
• Capable of driving up to ten LS-TTL loads while maintaining speeds comparable to low-power Schottky TTL circuits.

Applications

• Memory address decoding systems
• Data routing applications
• High-speed digital logic circuits

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current documentation to confirm lead status and RoHS compliance details. Ensure the DIP-24 package type matches the target PCB footprint requirements. Confirm that the operating temperature range meets the environmental specifications of the final assembly.

Selection Notes

Select this component when a decoded output with latched address inputs is required for high-speed CMOS designs. The HC series offers compatibility with standard logic families. Verify that the 2 V to 6 V supply range aligns with the system power architecture. Consider the DIP-24 package constraints for through-hole mounting strategies.

Part Context

This part belongs to the Texas Instruments CD74HC4514 family of decoders and demultiplexers. The 'E' designation indicates a DIP-24 package, while 'G4' typically signifies lead-free construction and specific manufacturing revisions. It serves as a functional equivalent to other industry-standard 4-to-16 decoders within the 74HC logic family.

Replacement Considerations

Cross-reference with MM74HC4514WMX for pin-compatible alternatives from Fairchild Semiconductor. Verify electrical parameters such as propagation delay and drive capability against the original datasheet specifications before substitution.
