Quad 2Input Multiplexer
with 3State Outputs
The MC74AC257/74ACT257 is a quad 2input multiplexer with
3state 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) input, allowing the outputs to interface directly
with busoriented systems.
Multiplexer Expansion by Tying Outputs Together
Noninverting 3State Outputs
Outputs Source/Sink 24 mA
′ACT257 Has TTL Compatible Inputs
