HEF4555BP,652

Overview

The HEF4555BP,652 is a dual 1-of-4 decoder/demultiplexer from the HE4000B CMOS logic family. It contains two independent decoders, each with two address inputs (nA0, nA1), an active LOW enable input (nE), and four mutually exclusive active HIGH outputs (nY0 to nY3). The device operates within a supply voltage range of 3 V to 15 V referenced to ground. It features high noise immunity, fully static operation, and standardized symmetrical output characteristics compliant with JEDEC JESD 13-B standards.

Feature Summary

• Contains two independent 1-of-4 decoders or demultiplexers with active HIGH outputs
• Operates over a wide recommended supply voltage range from 3.0 V to 15.0 V
• Provides ESD protection exceeding 2000 V for Human Body Model and 1000 V for Charged Device Model
• Ensures high noise immunity and fully static operation capabilities

Applications

• Code conversion
• Address decoding
• Demultiplexing using the enable input as data input

Procurement Notes

Verify the specific suffix '652' against the manufacturer's current ordering information to confirm package type and availability status. Confirm that the component meets required environmental specifications and lead times before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring dual 1-of-4 decoding functions in a single package. Ensure the application environment stays within the -40 °C to +85 °C operating temperature range and respects the absolute maximum ratings for supply voltage and current limits.

Part Context

This part belongs to the Nexperia HE4000B series of CMOS logic devices. The HEF4555B family provides versatile digital logic solutions for encoding and decoding tasks. The 'BP' designation typically indicates a PDIP-16 through-hole package variant within this product line.

Replacement Considerations

Check for cross-reference compatibility with other manufacturers offering equivalent 1-of-4 decoder ICs in similar packages. Verify pinout alignment and electrical parameter matching before substituting.
