The SN74LVC2G157DCUT is a 2-to-1 single Data Selector/Multiplexer designed for 1.65 to 5.5V VCC operation. It features a common strobe (G\\) input. When the strobe is high, Y is low and Y is high. When the strobe is low, a single bit is selected from one of two sources and is routed to the outputs. The device provides true and complementary data. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
Maximum tpd of 6ns 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)
Ioff Supports live insertion, partial-power-down mode and back-drive protection
Can be used as a down translator to translate inputs from a maximum of 5.5V down to the VCC level
Latch-up performance exceeds 100mA per JESD78 class II
