HCF4555BE is a CMOS dual 1-of-4 decoder/demultiplexer manufactured by STMicroelectronics (ST).

The HCF4555BE is a CMOS dual 1-of-4 decoder/demultiplexer manufactured by STMicroelectronics (ST).

Specifications:

  • Supply Voltage Range (VDD): 3V to 20V
  • Low Power Consumption: CMOS technology ensures minimal power dissipation
  • High Noise Immunity: Typical of CMOS devices
  • Operating Temperature Range: -55°C to +125°C
  • Package: DIP-16 (Dual In-line Package, 16 pins)
  • Logic Family: CMOS

Descriptions:

The HCF4555BE consists of two independent 1-of-4 decoders/demultiplexers. Each decoder has two binary select inputs (A and B) and an enable input (E). When enabled, the selected output (Y0 to Y3) goes HIGH based on the binary input combination.

Features:

  • Dual 1-of-4 Decoder/Demultiplexer: Two independent decoders in a single IC
  • Wide Operating Voltage: Supports 3V to 20V
  • Low Quiescent Current: Suitable for battery-operated applications
  • High-Speed Operation: Compatible with most logic families
  • Buffered Inputs and Outputs: Improved noise immunity and drive capability

This IC is commonly used in digital systems for address decoding, data routing, and control applications.
