CD4051BPW

CD4051BPW Description

The CD4051BPW from Texas Instruments is a high-performance 8:1 analog multiplexer/demultiplexer IC designed for precision signal routing in mixed-signal systems. Housed in a 16-pin TSSOP package, it features low on-state resistance (240Ω max) and minimal channel-to-channel matching (ΔRon = 5Ω), ensuring consistent signal integrity. With a wide supply voltage range (3V–20V single or ±2.5V–9V dual), it supports both single-ended and differential signal handling. The device offers low leakage current (100nA max) and low parasitic capacitance (0.2pF CS(off), 30pF CD(off)), making it suitable for high-frequency applications up to 20MHz bandwidth.

CD4051BPW Features

• Low Power Consumption: Ideal for battery-operated devices due to minimal leakage.
• High Signal Fidelity: Tight ΔRon and low capacitance reduce crosstalk and distortion.
• Broad Voltage Compatibility: Supports single/dual supplies, enabling flexible system integration.
• Robust Performance: ROHS3 compliant and REACH unaffected, meeting environmental standards.
• Reliable Packaging: MSL 1 (Unlimited) rating ensures long shelf life and handling ease.
• High Bandwidth: 20MHz -3dB bandwidth suits audio, video, and data acquisition systems.
