74AC257 74ACT257  
Quad 2-Input Multiplexer with 3-STATE Outputs  
General Description  
Features  
The AC/ACT257 is a quad 2-input multiplexer with 3-  
STATE outputs. Four bits of data from two sources can be  
selected using a Common Data Select input. The four out-  
puts present the selected data in true (noninverted) form.  
The outputs may be switched to a high impedance state by  
placing a logic HIGH on the common Output Enable (OE)  
input, allowing the outputs to interface directly with bus-ori-  
ented systems.  
ICC and IOZ reduced by 50%  
Multiplexer expansion by tying outputs together  
Noninverting 3-STATE outputs  
Outputs source/sink 24 mA  
ACT257 has TTL-compatible inputs
