74LS257 Overview
Key Specifications
Package: PDIP
Mount Type: Through Hole
Pins: 16
Operating Voltage: 5 V
Description
These Schottky-clamped high-performance multiplexers feature 3-STATE outputs that can interface directly with data lines of bus-organized systems. With all but one of the common outputs disabled (at a high impedance state), the low impedance of the single enabled output will drive the bus line to a HIGH or LOW logic level.
