MC74AC253 Datasheet, PDF (1/11 Pages) ON Semiconductor – Dual 4−Input Multiplexer with 3−State Outputs

MC74AC253, MC74ACT253
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
