CD54HC4052F3A

Analog Switches, Multiplexers, Demultiplexers Overview

The CD54HC4052F3A is a high-speed CMOS analog multiplexer/demultiplexer manufactured by Texas Instruments. It features two independent 4-to-1 channels with bidirectional switching capabilities. The device operates within a supply voltage range of 2V to 6V for HC types and supports an analog input voltage range from VEE to VCC. Key electrical parameters include a typical ON-resistance of 70Ω at VCC–VEE = 4.5V and 40Ω at 9V, with a maximum ON-resistance variation (ΔrON) of 10Ω. It exhibits low crosstalk, break-before-make switching, and direct LSTTL/CMOS logic compatibility. The component is designed for military-grade reliability with an operating temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Bidirectional analog signal routing between common terminals and four selectable channels per switch section
• Low ON-resistance with minimal variation across channels for accurate signal transmission
• Break-before-make switching action prevents momentary short circuits during channel transitions
• Active-low enable control allows disabling all switches simultaneously to the OFF state

Analog Switches, Multiplexers, Demultiplexers Applications

• Digital radio systems requiring signal gating and routing
• Factory automation control circuits
• Programmable logic circuit implementations
• Sensor interface networks

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix F3A against the manufacturer's current datasheet to confirm package type and material specifications. Ensure the procurement source provides valid traceability documentation for the CD54 series military-grade components. Confirm RoHS compliance status as historical data indicates non-compliance for some variants in this family.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the CD54HC4052F3A when military-grade temperature stability (-55°C to +125°C) is required. Choose this part over the CD74 variant if ceramic packaging offers necessary environmental protection. Verify that the system supply voltage remains within the 2V to 6V range for optimal ON-resistance performance. Ensure logic levels match the HC family requirements rather than HCT thresholds.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the CDx4HC405x family of high-speed CMOS analog multiplexers. It shares functional similarities with the CD54HC4051 (8:1) and CD54HC4053 (3:2), differing primarily in channel count and configuration. The CD54 prefix denotes military-grade qualification, distinguishing it from the commercial CD74 series while maintaining pin-out compatibility within the same logical family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitutes include the CD74HC4052 for commercial applications and the CD54HCT4052 for LSTTL-compatible logic interfaces. Verify package equivalence before substitution.
