CD74HC4051PWT

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4051PWT is a high-speed CMOS analog multiplexer/demultiplexer manufactured by Texas Instruments. It features an 8:1 configuration with a single circuit, housed in a 16-TSSOP surface-mount package. The device operates on a single supply voltage ranging from 2V to 6V or dual supplies of ±1V to ±5V. Key electrical parameters include a maximum on-resistance of 130 ohms and a channel-to-channel matching of 5 ohms. It supports a -3dB bandwidth of 180MHz, with off-state leakage current capped at 400nA and channel capacitance at 25pF. The component functions reliably within an ambient temperature range of -55°C to 125°C.
