MC74AC253, MC74ACT253
Dual 4Input Multiplexer
with 3State Outputs
The MC74AC253/74ACT253 is a dual 4input multiplexer with
3state 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 3State Outputs
Outputs Source/Sink 24 mA
′ACT253 Has TTL Compatible Inputs
