CD74HC4052E

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4052E is a dual 4:1 analog multiplexer/demultiplexer manufactured by Texas Instruments in the HC logic family. It features two independent multiplexers, each with four inputs and one common output, controlled by shared address lines. 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, a -3dB bandwidth of 185MHz, and an off-state leakage current of 200nA. It is housed in a 16-pin PDIP package and supports an operating temperature range from -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' corresponds to the 16-pin PDIP package configuration when sourcing. Confirm RoHS compliance status, as historical revisions may vary. Ensure the supplier provides official datasheets matching the CDx4HC405x series documentation. Check for any recent Product Change Notifications regarding packaging or material composition updates.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent analog switching is required within a single package. The HC logic family offers compatibility with standard CMOS logic levels. Consider the 130-ohm on-resistance limit for signal integrity requirements. Verify that the 185MHz bandwidth meets the frequency specifications of the signals being routed. Ensure the 16-pin DIP package fits the target PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Texas Instruments CD74HC405x series, which includes variants like the CD74HC4051 (8:1) and CD74HC4053 (3:2). The 'CD' prefix indicates commercial grade availability, while 'HC' denotes High-speed CMOS technology. The 'E' suffix specifically identifies the through-hole PDIP package variant, distinguishing it from surface-mount options like NSR or M.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes include the CD74HC4052NSR (SOIC package) and CD74HC4052PWRE4 (TSSOP package). Cross-brand equivalents such as the HEF4052B are available but may differ in speed and drive strength. Verify that alternative packages maintain the same electrical characteristics and thermal performance.
