Texas Instruments SN74AHC157/SN74AHC157-Q1 2-to-1 Data Selector/Mux
Texas Instruments SN74AHC157/SN74AHC157-Q1 Quad 2-to-1 Line Data Selectors/Multiplexers are designed for 2V to 5.5V VCC operation. The SN74AHC157/SN74AHC157-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 SN74AHC157-Q1 devices are AEC-Q100 qualified for automotive applications.
Features
- Operating range 2V to 5.5V
- The device contains four 2:1 multiplexers
- Low delay of 12ns (VCC = 5V, CL = 50pF)
- Latch-up performance exceeds 250mA per JESD 17
- ESD protection exceeds JESD 22
- 2000V human-body model (A114-A)
- 200V machine model (A115-A
- 1000V charged-device model (C101)
Applications
- Memory device selection with shared data bus
- Route data
- Reduce the required number of outputs for chip-select applications
