Dual 4-Input Multiplexer
with 3-State Outputs
The MC74AC253/74ACT253 is a dual 4–input multiplexer with
3–state outputs. It can select two bits of data from four sources using
common select inputs. The outputs may be individually switched to a
high impedance state with a HIGH on the respective Output Enable
(OE) inputs, allowing the outputs to interface directly with bus
oriented systems. Multifunctional Capability Noninverting 3–State Outputs Outputs Source/Sink 24 mA ′ACT253 Has TTL Compatible Inputs
