CD4051BPWR

CD4051BPWR Description

The CD4051BPWR 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 compact 16-pin TSSOP package, it features low on-state resistance (240Ω max) and minimal leakage current (100nA max), ensuring efficient signal integrity. The device supports single-supply (3V–20V) or dual-supply (±2.5V–9V) operation, making it versatile for both low-voltage and bipolar applications. With a -3dB bandwidth of 20MHz and low channel capacitance (0.2pF off-state, 30pF on-state), it excels in high-frequency and low-distortion scenarios.

CD4051BPWR Features

• Low On-Resistance: 240Ω max ensures minimal signal attenuation.
• Wide Voltage Range: Operates from 3V–20V (single) or ±2.5V–9V (dual), accommodating diverse power requirements.
• High Bandwidth: 20MHz -3dB bandwidth suits high-speed signal switching.
