HEF4515BT,652

Overview

The HEF4515BT,652 is a dual 4-to-16 line decoder/demultiplexer from the NXP HEF4000B series. It operates within a supply voltage range of 3 V to 15 V and supports surface-mount installation in an SO16 package. The device features two independent decoding circuits with active LOW outputs and includes dedicated address strobe inputs for data control. It functions across an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Dual independent 4-to-16 line decoding capability
• Active LOW output logic states
• Dedicated address strobe inputs for precise timing control

Applications

• Data routing and demultiplexing
• Memory address decoding
• Control signal distribution

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Ensure the component meets the required operating temperature range for the intended application environment.

Selection Notes

Select this component when dual independent decoding channels are required in a compact surface-mount form factor. Verify that the logic family voltage compatibility matches the system design requirements. Consider the SO16 package dimensions for PCB layout constraints compared to through-hole alternatives.

Part Context

This part belongs to the HEF4000B series of CMOS logic devices manufactured by Nexperia (formerly NXP Semiconductors). The series provides standard logic functions optimized for general-purpose digital applications. The 'BT' designation indicates a surface-mount SOIC package variant.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent 4000-series CMOS dual decoders. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive current before substitution.
