HCF4051 is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology.

The HCF4051 is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology. It is a single 8-channel analog multiplexer/demultiplexer manufactured by STMicroelectronics.

Key Specifications:

  • Supply Voltage Range (VDD to VSS): 3V to 20V
  • Analog Input Voltage Range (VSS ≤ VI ≤ VDD): Supports rail-to-rail analog signals
  • Low ON Resistance:
  • 80Ω (typical) at VDD - VSS = 15V
  • 120Ω (typical) at VDD - VSS = 10V
  • 240Ω (typical) at VDD - VSS = 5V
  • Low OFF Leakage Current: 0.1nA (typical) at VDD - VSS = 18V, TA = 25°C
  • High OFF Isolation: -50dB (typical) at f = 1MHz
  • Crosstalk Rejection: -50dB (typical) at f = 1MHz
  • Operating Temperature Range: -55°C to +125°C
  • Package Options: DIP-16, SO-16

Features:

  • Channel Selection: 3 binary control inputs (A, B, C) and an inhibit input
  • Break-Before-Make Switching: Prevents signal overlap during switching
  • Wide Analog Signal Range: Can handle signals from VSS to VDD

Applications:

  • Analog and digital multiplexing/demultiplexing
  • Signal gating
  • A/D and D/A conversion
  • Communication systems
