Dual 4:1 multiplexer in a 16-SOIC footprint
The MC74ACT153DG: It selects one of four data inputs per multiplexer based on a common two-bit address, routing the chosen signal to the corresponding output. Operating from a single 4.5V to 5.5V supply, it is a direct fit for 5V TTL/CMOS logic systems. The 16-SOIC footprint (Supplier Device Package 16-SOIC) is a standard narrow-body SOIC, which means the PCB land pattern is well-documented and shared across many logic and interface parts — no custom footprint required.
Output drive and temperature range
The 74ACT family's 5V swing and 24mA drive are well matched to the noise margins of a 5V backplane or a sensor bus running at 3.3V with level translation.
