MC74ACT253
Dual 4ĆInput Multiplexer
with 3ĆState 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
