CD4051

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
