HEF4514BP,652

Overview

The HEF4514BP,652 is a 1-of-16 decoder/demultiplexer from the HEF4000B logic family. It features four binary weighted address inputs (A0 to A3), a latch enable input (EL), and an active LOW enable input (E). The device provides 16 mutually exclusive active HIGH outputs (O0 to O15). When EL is HIGH, output selection follows address inputs; when EL goes LOW, the last data state is stored in internal latches. The component operates within a supply voltage range of 3 V to 15 V.

Feature Summary

• Integrates input latching capability to maintain stable output states independent of subsequent address changes
• Supports dual functionality as both a 1-of-16 decoder and a demultiplexer via configurable pin usage
• Features mutually exclusive active HIGH outputs for precise signal routing

Applications

• Digital multiplexing systems
• Address decoding circuits
• Hexadecimal or BCD decoding applications

Procurement Notes

Verify that the specific ordering suffix matches the required package type. Confirm the manufacturer designation aligns with current NXP Semiconductor specifications. Ensure compliance with relevant RoHS directives before finalizing procurement orders.

Selection Notes

Select this component when system design requires decoded signals with persistent state retention. The integrated latching function eliminates the need for external storage elements. Verify that the operating voltage range accommodates the specific circuit requirements.

Part Context

This part belongs to the HEF4000B MSI logic family manufactured by NXP Semiconductors. It utilizes LOCMOS technology and is available in various package configurations including plastic DIP and SO types. The datasheet originates from Philips Semiconductors documentation archives.

Replacement Considerations

Cross-reference with HEF4514BT(D) for surface mount alternatives. Verify compatibility with HEF4514BD(F) ceramic packages if environmental constraints require hermetic sealing.
