CD74HCT4052EG4

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HCT4052EG4 is a high-speed CMOS analog multiplexer/demultiplexer manufactured by Texas Instruments. It features two independent 4-to-1 channels with TTL-compatible inputs, enabling efficient signal routing in digital and mixed-signal systems. The device operates on a single supply voltage ranging from 4.5V to 5.5V or dual supplies of ±1V to ±5V. Packaged in a 16-pin SOIC (N) format, it supports surface-mount assembly. Key electrical characteristics include a maximum on-resistance of 130 ohms, a channel-to-channel matching of 5 ohms, and a -3dB bandwidth of 185MHz. It functions reliably across an extended industrial temperature range from -55°C to +125°C.
