CD74ACT157E TI Multiplexer | 16-PDIP | 4.5V-5.5V, 4-Channel 2:1

Product Overview

The CD74ACT157E is a high-speed quad 2-input multiplexer from Texas Instruments, featuring four independent 2:1 multiplexer channels. It operates from a 4.5V to 5.5V supply and is housed in a 16-pin PDIP package. This device selects one of two 4-bit data sources under control of a common Select input (S). The outputs are enabled by an active-low Output Enable (OE) input. When OE is high, all outputs are forced to a low state, regardless of the Select or data inputs. The CD74ACT157E is designed for high-performance digital systems requiring fast propagation delays and low power consumption.
