IC 74LS157 QUAD 2-TO-1 LINE DATA SELECTOR

8-Input NAND Gate

Specifications

These data selectors/multiplexers contain inverters and drivers to supply full on-chip data selection to the four output gates. A separate strobe input is provided. A 4-bit word is selected from one of two sources and is routed to the four outputs. The DM74LS157 presents true data whereas the DM74LS158 presents inverted data to minimize propagation delay time.

Applications

Expand any data input point

Multiplex dual data buses

Generate four functions of two variables (one variable is common)

Source programmable counters

Features

Buffered inputs and outputs

Typical Propagation Time: 9 ns

Typical Power Dissipation: 49 mW
