The SN74LVC157A SN74LVC157A features 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 device provides true data. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment. The SN74LVC157A SN74LVC157A is characterized for operation from ­40°C to 85°C.
