CD74HC4514ENG4

Overview

The CD74HC4514ENG4 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 address latches. The component operates within a supply voltage range of 2 V to 6 V and supports surface-mount or through-hole installation styles. It features a propagation delay of 23 ns and includes four input lines and sixteen output lines. The device is housed in a 24-pin DIP package and is rated for operation between -55°C and +125°C.

Feature Summary

• Integrates address latches to capture input data before decoding
• Provides simultaneous decoding and demultiplexing capabilities
• Supports wide operating temperature ranges for industrial environments

Applications

• Data routing in digital communication systems
• Memory addressing circuits
• Display driver interfaces

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free composition and environmental compliance per manufacturer standards. Confirm the package type matches design requirements, as variants exist in SOIC and DIP formats. Ensure the logic family aligns with system voltage levels. Cross-reference datasheet revisions for any pinout or electrical characteristic updates prior to final procurement.

Selection Notes

Select this component when a 4-bit binary code must be decoded into one of sixteen active-low outputs. The integrated latch feature simplifies timing constraints by holding address inputs stable during decoding. Verify that the HC series speed and power consumption meet the system's performance needs compared to HCT or AC alternatives.

Part Context

This part belongs to the CD74HC4514 family of decoders and demultiplexers. It shares functional similarities with other 4-to-16 line devices but is distinguished by its specific latch configuration and HC series electrical characteristics. The 'E' designation typically refers to the DIP package style, while 'G4' denotes environmental compliance attributes defined by Texas Instruments.
