74HC253D-Q100,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74HC253D-Q100,118 is a dual 4-input multiplexer with 3-state outputs, qualified to AEC-Q100 Grade 1 for automotive use. It features two independent multiplexers sharing common select inputs (S0, S1) and separate output enable inputs (nOE). The device operates within a supply voltage range of 2.0 V to 6.0 V and supports CMOS input levels. It includes clamp diodes on all inputs, allowing current limiting resistors for interfacing with voltages exceeding VCC. The component is housed in an SO16 plastic small outline package (SOT109-1) and is specified for ambient temperatures from -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this part when designing systems requiring dual 4-to-1 multiplexing with high-impedance states. Ensure the application voltage remains within the 2.0 V to 6.0 V range. For mixed-voltage environments where inputs exceed VCC, utilize external current-limiting resistors leveraging the internal clamp diodes. Confirm that the SO16 package fits the PCB layout constraints and that the operating temperature range meets the environmental requirements.

Signal Switches, Multiplexers, Decoders Part Context

This component belongs to the Nexperia 74HC_HCT253_Q100 family of dual 4-input multiplexers. It is specifically the HC variant, distinguished by CMOS input levels, as opposed to the HCT variant which uses TTL levels. Both variants share identical pinouts and functional descriptions but differ in input voltage thresholds. The D-Q100 designation indicates the SO16 package and automotive qualification.
