Texas Instruments SN74AHCT157/SN74AHCT157-Q1 Data Sel/Multiplexers
Texas Instruments SN74AHCT157/SN74AHCT157-Q1 Quad 2-to-1 Line Data Selectors/Multiplexers are designed for 4.5V to 5.5V VCC operation. The SN74AHCT157/SN74AHCT157-Q1 devices feature a common strobe (G) input. When the strobe is high, all outputs are low. When the strobe is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. The devices provide true data. The Texas Instruments SN74AHCT157-Q1 devices are AEC-Q100 qualified for automotive applications.
Features
