G4676A - 74ACT157 Quad Non-Inverting 2-Input Multiplexer

This quadruple 2-line to 1-line data selector/multiplexer is designed for 4.5-V to 5.5-V VCC operation. The 74ACT157 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.

Features:
Inputs Are TTL-Voltage Compatible
Speed of Bipolar F, AS, and S, With Significantly Reduced Power Consumption
Balanced Propagation Delays
±24-mA Output Drive Current
Fanout to 15 F Devices
SCR-Latchup-Resistant CMOS Process and Circuit Design
