74HCT4514PW118

Signal Switches, Multiplexers, Decoders Overview

The 74HCT4514PW,118 is a 4-to-16 line decoder/demultiplexer with input latches manufactured by Nexperia. It features four binary weighted address inputs (A0 to A3), a latch enable input (LE), an enable input (E), and 16 outputs (Q0 to Q15). The device operates within a supply voltage range of 4.5 V to 5.5 V for the HCT variant. It utilizes a TSSOP24 plastic thin shrink small outline package (SOT355-1) and supports an operating temperature range from -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Decodes four binary-coded inputs into 16 mutually-exclusive outputs
• Includes input latches that store data when the latch enable signal transitions LOW
• Features reduced input threshold levels compatible with TTL logic levels

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when interfacing with TTL logic levels is required due to its HCT input thresholds. Ensure the design accommodates the TSSOP24 package dimensions and thermal requirements for the specified industrial temperature range. Confirm that the application does not exceed the absolute maximum ratings for supply voltage or output current.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74HCT series of logic ICs, which are designed for compatibility with standard TTL logic families while offering CMOS low power dissipation. The 74HCT4514 specifically provides decoding and demultiplexing capabilities with integrated latching functionality, distinguishing it from non-latched variants in the same family.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74HC4514PW is a related variant within the same product family but operates with CMOS input levels rather than TTL levels. Verify interface voltage compatibility before substitution.
