Details

National Semiconductor 74ACT257SCX Quad Multiplexer / Demultiplexer 3-State 4.5 V-5.5V SMT / SMD SOIC-16

The 74ACT257 is an advanced high-speed CMOS QUAD 2-CHANNEL MULTIPLEXER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C 2 MOS tecnology. It is composed of an independent 2-channel multiplexer with common SELECT and ENABLE (OE )inputs. It is a non-inverting multiplexer. When the ENABLE input is held HIGH, the outputs are forced to a high impedance state.
