CD74HCT4052E

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HCT4052E is a high-speed CMOS analog multiplexer manufactured by Texas Instruments, originally part of the Harris Corporation product lineage. It features two independent 4-to-1 multiplexers in a 16-pin DIP package. The device operates with TTL-compatible inputs and supports single supply voltages from 2V to 10V or dual supplies from ±1V to ±5V. 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 within an extended temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify manufacturer origin as Texas Instruments handles current production of the CD74 series. Confirm RoHS compliance status for specific manufacturing lots. Check for obsolescence notices regarding legacy Harris Corporation stock. Ensure packaging matches the required 16-DIP format for through-hole assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when TTL compatibility is required alongside analog switching capabilities. Compare against HC variants if lower power consumption is critical, noting HCT inputs have different threshold characteristics. Verify voltage requirements align with the 2V to 10V single supply range. Consider package availability as DIP formats may have longer lead times than surface mount alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the CD74HCT405x family of analog switches. It shares functional similarities with the CD74HC4052 but utilizes HCT logic inputs for better compatibility with standard TTL logic families. The device is widely used in mixed-signal designs where digital control interfaces with analog signal paths.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

CD74HC4052E offers similar functionality with HC logic inputs instead of HCT. CD74HCT4052M96 provides the same electrical performance in a surface-mount SOIC package. Nexperia 74HCT4052DB serves as a pin-compatible alternative from a different manufacturer.
