CD54HC4053F3A

Analog Switches, Multiplexers, Demultiplexers Overview

The CD54HC4053F3A is a high-speed CMOS analog multiplexer/demultiplexer housed in a 16-lead ceramic dual in-line package (CDIP). It integrates three independent 2-to-1 channels controlled by binary address inputs. The device supports a supply voltage range of 2V to 6V for HC types, with an analog signal range spanning from VEE to VCC. Key electrical parameters include a typical ON-resistance of 70Ω at 4.5V supply and 40Ω at 9V supply. It operates within a temperature range of -55°C to +125°C and features low crosstalk, break-before-make switching, and direct LSTTL input compatibility.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates three independent bidirectional 2-to-1 analog switches within a single package.
• Features low ON-resistance and low OFF leakage currents for efficient signal routing.
• Provides break-before-make switching action to prevent signal shorting during channel transitions.
• Supports wide analog input voltage ranges extending across the full power supply rails.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix F3A against current Texas Instruments documentation to confirm package type and environmental compliance. Ensure the procurement source provides valid traceability for military-grade specifications associated with the CD54 prefix. Confirm availability status as legacy or active through official TI channels before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the CD54HC4053F3A when military-grade temperature stability (-55°C to +125°C) and ceramic packaging reliability are required. Choose this part over the CD74 variant if radiation hardness or harsh environment performance is necessary. Verify that the 2-to-1 channel configuration meets system requirements, as other variants offer 4-to-1 or 8-to-1 options.

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-to-1) and CD54HC4052 (dual 4-to-1), differing primarily in channel count and configuration. The CD54 prefix indicates military-grade qualification, distinguishing it from commercial CD74 equivalents.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitutes include CD54HC4053FL and CD54HC4053FK. Verify pinout compatibility and electrical characteristics match before substitution. Commercial alternatives like CD74HC4053 lack the military temperature rating and ceramic package.
