CD74HCT4053E

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HCT4053E is a triple 2-channel single-ended analog multiplexer/demultiplexer manufactured by Texas Instruments, originally part of the Harris Corporation logic portfolio. It operates within a supply voltage range of 4.5V to 5.5V and features three independent SPDT switch circuits. Key electrical parameters include a maximum on-resistance of 130 ohms, a channel-to-channel matching of 5 ohms, and an off-state leakage current of 100nA. The device supports a -3dB bandwidth of 200MHz and offers propagation delays of approximately 12ns. It is housed in a 16-pin PDIP package with an operating temperature range from -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Provides three independent single-ended analog switching channels controlled by digital select inputs.
• Capable of handling both AC and DC signals when supplied with dual power rails or ground-referenced single supply.
• Features low off-state leakage current and high input impedance suitable for precision signal routing.

Analog Switches, Multiplexers, Demultiplexers Applications

• Audio signal path switching and routing in consumer electronics.
• DC control voltage selection in industrial instrumentation.
• Data acquisition systems requiring multi-channel signal conditioning.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin carefully, as the CD74HCT4053E was historically produced by Harris Corporation before being acquired by National Semiconductor and subsequently Texas Instruments. Ensure the specific lot date code aligns with your supply chain requirements. Confirm RoHS compliance status if environmental regulations apply to your deployment. Cross-reference the datasheet version to ensure pinout and electrical characteristics match your design specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when three independent 2:1 analog switches are required in a single package. The HCT logic series ensures compatibility with standard TTL voltage levels. Consider the 130-ohm on-resistance limit for signal integrity in high-impedance circuits. The wide industrial temperature range makes it suitable for harsh environments compared to commercial-grade alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the 74HCT4053 family of analog multiplexers. While originally associated with Harris Corporation's logic products, current production and documentation are managed by Texas Instruments following industry consolidations. It serves as a direct functional replacement for other 74HCT4053 variants from different manufacturers, provided pinouts and electrical limits are compatible.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the CD74HC4053E (HC series) and NXP 74HCT4053N. Verify that the alternative package type matches your PCB footprint. Check if the replacement offers improved on-resistance or bandwidth if signal fidelity is critical.
