74HCT4515N,652

Signal Switches, Multiplexers, Decoders Overview

The NXP USA Inc. 74HCT4515N,652 is a high-speed silicon-gate CMOS logic device belonging to the 74HCT series. It functions as a 4-to-16 line decoder and demultiplexer with input latches. The component features inverting outputs and is designed for through-hole mounting in a standard 24-pin PDIP package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40 °C to +125 °C. The device complies with JEDEC standard no. 7A specifications.

Signal Switches, Multiplexers, Decoders Feature Summary

• Integrates address latching capability to store selection inputs independently of data decoding operations
• Provides inverting output polarity suitable for active-low signal routing applications
• Ensures TTL-compatible input levels for direct interfacing with standard logic families

Signal Switches, Multiplexers, Decoders Applications

• Data routing systems requiring decoded address selection
• Memory addressing circuits utilizing latch-based control
• Industrial control panels needing robust CMOS decoding

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix '652' against official NXP documentation to confirm exact tape-and-reel or tube packaging details. Ensure the order matches the PDIP-24 through-hole form factor required by the target PCB layout. Confirm RoHS compliance status directly with the manufacturer's current product change notifications prior to final procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS power efficiency. The integrated latches distinguish it from non-latched decoders like the 74HCT154. Verify that the 24-pin DIP package fits the assembly constraints. Consider the extended industrial temperature range if the application environment exceeds standard commercial limits.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the widely used 74HCT logic family, which bridges the gap between older 74LS performance and modern CMOS power consumption. The 4515 variant specifically adds latching functionality compared to the base 4514/4515 architecture. It serves as a standard interface component in digital systems requiring stable address decoding.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The CD74HCT4515EN from Texas Instruments offers identical logical function and pinout compatibility. Other manufacturers such as Nexperia produce equivalent parts under the 74HCT4515 designation. Verify package dimensions and electrical tolerances before substituting.
