CD74HC4352E

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4352E is a dual 4-to-1 multiplexer manufactured by Texas Instruments, utilizing high-speed CMOS technology. It operates on a single supply voltage ranging from 2V to 6V or dual supplies of ±1V to ±5V. The device features two independent SP4T switching circuits with a maximum on-resistance of 130 ohms and channel-to-channel matching of 5 ohms. Switching times are specified at a maximum of 60ns for turn-on and 55ns for turn-off. It is housed in a 20-pin PDIP package and supports an operating temperature range of -55°C to 125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer designation as Texas Instruments rather than Harris Corporation, as the specific part number CD74HC4352E corresponds to TI production. Confirm the package type is 20-PDIP and check for RoHS compliance status. Ensure the component meets the required operating temperature range of -55°C to 125°C for your specific application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 4:1 multiplexing is required within a single package. It is suitable for applications needing low on-resistance and fast switching speeds under standard CMOS logic levels. Consider the 20-pin DIP form factor for through-hole mounting requirements and verify that the 2V to 6V supply range aligns with system power constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. It functions as an analog switch/multiplexer, distinct from digital logic gates. The 'CD' prefix typically denotes commercial grade temperature range variants within the broader 74HC family lineage.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The CD74HC4052M96 is listed as a manufacturer-recommended substitute. Verify pinout compatibility and electrical parameter equivalence before substitution.
