MC74HC4053AF

Analog Switches, Multiplexers, Demultiplexers Overview

The MC74HC4053AF is a triple single-pole double-throw (SPDT) analog multiplexer/demultiplexer manufactured by onsemi. It utilizes silicon-gate CMOS technology to achieve fast propagation delays, low ON resistance, and low OFF leakage currents. The device controls analog voltages varying across the complete power supply range from VCC to VEE. It features three independent switches with common outputs/inputs, controlled by channel-select inputs A, B, and C. When the Enable pin is HIGH, all analog switches are turned off. The digital control inputs are compatible with standard CMOS outputs and LSTTL outputs when pullup resistors are used.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'F' corresponds to the SOEIAJ-16 package (Case 966) as listed in the ordering information. Confirm RoHS compliance status through official manufacturer declarations or datasheet environmental sections before procurement. Ensure the component source is an authorized distributor to guarantee authenticity and traceability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a triple SPDT analog switch is required within a compact SOEIAJ-16 footprint. Verify that the operating voltage range of 2.0V to 6.0V for digital supplies and up to 12.0V total analog swing meets system requirements. Consider the maximum ON resistance and leakage current specifications against the signal integrity needs of the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MC74HC405xA family, which includes the HC4051A (8:1 MUX) and HC4052A (Dual 4:1 MUX). All devices share identical pinouts with their metal-gate MC1405xAB predecessors. The HC4053A specifically integrates 156 FETs or 39 equivalent gates, offering a balanced solution for multi-channel analog switching tasks.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include other manufacturers' 74HC4053 variants such as the SN74HC4053 or CD74HC4053. Verify electrical parameters like ON resistance and propagation delay match the original design constraints. Package compatibility must be confirmed if substituting with different package suffixes.
