description

The 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 is characterized for operation from –40

°C to 85°C.
