54AC257 54ACT257  
Quad 2-Input Multiplexer with TRI-STATE® Outputs  
General Description  
Features  
n ICC and IOZ reduced by 50%  
n Multiplexer expansion by tying outputs together  
n Noninverting TRI-STATE outputs  
n Outputs source/sink 24 mA  
The ’AC/’ACT257 is  
a quad 2-input multiplexer with  
TRI-STATE outputs. Four bits of data from two sources can  
be selected using a Common Data Select input. The four  
outputs 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) in-  
put, allowing the outputs to interface directly with  
bus-oriented systems.  
n ’ACT257 has TTL-compatible inputs  
n Standard Military Drawing (SMD)  
— ’AC257: 5962-88703  
— ’ACT257: 5962-89689
