CD4051BM Overview

Part: CD405xB from Texas Instruments

Type: CMOS Analog Multiplexer or Demultiplexer

Description: The CD405xB is a family of digitally-controlled analog switches featuring low ON impedance (125 Ω typical at VDD = 15V) and very low OFF leakage current (±10 pA typical at VDD = 15V), supporting digital supply voltages from 3V to 20V and analog signals up to 20VP-P.

Operating Conditions:

  • Supply voltage: 3V to 20V (single supply), ±3V to ±10V (dual supply)
  • Operating temperature: -55 to 125 °C
  • Analog signal levels: ≤ 20VP-P

Absolute Maximum Ratings:

  • Max supply voltage: 20 V (V+ to V-)
  • Max continuous current: 10 mA (Any One Input)
  • Max junction/storage temperature: 175 °C (ceramic package), 150 °C (plastic package), -65 to 150 °C (storage)

Key Specs:

  • Low ON resistance: 125 Ω (typical) at VDD = 15V, 0 ≤ VIS ≤ VDD, 25°C
  • Max ON resistance: 240 Ω (max) at VDD = 15V, 0 ≤ VIS ≤ VDD, 25°C
  • Channel leakage OFF: ±0.3 nA (typical) at VDD = 18V, 25°C
  • Quiescent device current: 60 μA (max) at VDD = 5V, 25°C
  • Input capacitance (CIS): 5 pF (typical) at VDD = 10V, 25°C
  • Output capacitance (COS): 30 pF (typical for CD4051) at VDD = 10V, 25°C
  • Propagation delay (Address-to-Signal OUT): 10 ns (typical) at VDD = 15V, CL = 50pF, RL = 10kΩ, 25°C

Features:

  • Wide range of digital and analog signal levels
  • Low ON resistance
  • Low channel leakage
  • Low quiescent power dissipation
  • Break-before-make switching eliminates channel overlap
  • Bidirectional signal path
  • ESD protection HBM: 3000V, CDM: 2000V
  • Pin compatible with industry standard 4051 muxes

Applications:

  • Analog and digital multiplexing and demultiplexing
  • Analog to digital and digital to analog conversion
  • Signal gating
  • Factory automation
  • Televisions
  • Appliances
  • Consumer audio
  • Programmable logic circuits
  • Sensors

Package:

  • J (CDIP, 16)
  • N (PDIP, 16)
  • D (SOIC, 16)
  • NS (SOP, 16)
  • PW (TSSOP, 16)

CD4051BM Features

  • Wide range of digital and analog signal levels:
  • -Digital: 3V to 20V
  • -Analog: ≤ 20VP-P
  • Single supply range : 3V to 20V (performance degrades for VDD < 3V)
  • Dual Supply range: ± 3V to ± 10V
  • Low ON resistance, 125Ω (typical) over input range for VDD = 15V
  • Low channel leakage of ±10pA (typical) at VDD = 15V
  • Low quiescent power dissipation : 0.2μW (typical)
  • Break-before-make switching eliminates channel overlap
  • Bidirectional signal path
  • ESD protection HBM: 3000V, CDM: 2000V
  • Pin compatible with industry standard 4051 muxes
