CD74HCT4051MT

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HCT4051MT is a high-speed CMOS analog multiplexer/demultiplexer manufactured by Texas Instruments. It features an 8:1 configuration with three binary address inputs and a low-active enable input, housed in a 16-SOIC surface-mount package. The device operates on a single supply voltage ranging from 4.5 V to 5.5 V, drawing a maximum supply current of 16 µA. Key electrical parameters include a -3dB bandwidth of 180 MHz, a maximum propagation delay of 49 ns, and an on-resistance of 130 Ω. It supports a dual power supply range of ±1 V to ±5 V and functions reliably within an operating temperature range of -55 °C to +125 °C.
