The SN74LVC157APW is a quadruple 2-to-1 Data Selector/Multiplexer designed for 1.65 to 3.6V VCC operation. It features a common strobe (G\\) input. When G\ is high, all outputs are low. When G\ is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. It provides true data. Inputs can be driven from either 3.3 or 5V devices. This feature allows the use of this device as translators in a mixed 3.3/5V system environment.
Latch-up performance exceeds 250mA per JESD 17
ESD protection exceeds JESD 22
Maximum tpd of 5.2ns at 3.3V
<0.8V at VCC = 3.3V, TA = 25°C Typical VOLP (output ground bounce)
>2V at VCC = 3.3V, TA = 25°C Typical VOHV (output VOH undershoot)
