HCF4051BE is a single 8-channel analog multiplexer/demultiplexer manufactured by STMicroelectronics (ST).

The HCF4051BE is a single 8-channel analog multiplexer/demultiplexer manufactured by STMicroelectronics (ST).

Specifications:

  • Supply Voltage Range (VDD - VSS): 3V to 20V
  • Analog Signal Range (VEE = VSS): ±5V (with 5V supply)
  • Low On-Resistance: 125Ω (typical) at VDD - VEE = 15V
  • Low Leakage Current: ±100pA (max) at TA = 25°C
  • High Noise Immunity: 0.8VDD (min)
  • Operating Temperature Range: -40°C to +85°C
  • Package: DIP-16

Descriptions:

  • The HCF4051BE is a CMOS-based analog switch that allows one of eight inputs to be connected to a common output (or vice versa).
  • It features three binary control inputs (A, B, C) and an inhibit input to enable/disable all switches.
  • Suitable for analog and digital signal switching.

Features:

  • Wide Voltage Range: Compatible with 3V to 20V supplies.
  • Low Power Consumption: CMOS technology ensures minimal power dissipation.
  • Break-Before-Make Switching: Prevents signal overlap during switching.
  • High Off-Isolation: Minimizes crosstalk between channels.
  • Logic-Level Translation: Can interface between different logic families (e.g., TTL to CMOS).

This device is commonly used in signal routing, data acquisition, and audio/video switching applications.
