The MC74HC4053AFELG is a triple single-pole double-throw (SPDT) analog multiplexer/demultiplexer manufactured by onsemi. It utilizes silicon-gate CMOS technology to provide fast switching speeds, low ON resistance, and low OFF leakage currents. The device features three independent switches, each capable of connecting one of two analog inputs or outputs to a common terminal. It operates with a digital supply voltage range of 2.0 V to 6.0 V and an analog signal range spanning from VEE to VCC, allowing for dual supplies up to ±6.0 V. The component is housed in a 16-lead SOEIAJ surface-mount package.
Verify the specific ordering suffix 'FELG' corresponds to the SOEIAJ-16 package and Pb-free status as defined in the manufacturer's documentation. Confirm that the lead marking format matches the official MC74HC405xA ALYW/C0071 diagram. Ensure compatibility with the required moisture sensitivity level and storage conditions specified in the datasheet before finalizing procurement orders.
Select this component when a triple SPDT analog switch is required within a compact SOEIAJ-16 footprint. Verify that the operating voltage requirements align with the 2.0 V to 6.0 V digital supply range. Consider the maximum ON resistance limits at the intended operating temperature if signal integrity is critical. Ensure the analog input voltage stays within the VEE to VCC range to prevent damage.
This part belongs to the MC74HC405xA family of analog multiplexers, which also includes the MC74HC4051A (8:1) and MC74HC4052A (4:2). All devices in this series share identical pinouts and utilize similar silicon-gate CMOS technology. The MC74HC4053A specifically offers three independent 2:1 switches, distinguishing it from the higher-channel-count variants while maintaining compatible control logic and electrical characteristics.
Direct functional substitutes include other HC4053 variants from different manufacturers such as the SN74HC4053 or CD4053 series. When replacing, verify that the alternative package type matches the SOEIAJ-16 dimensions or requires PCB re-layout. Ensure the replacement device supports the same analog voltage swing and propagation delay specifications required by the circuit design.
