MC74ACT353

Manufacturer Part Number
MC74ACT353
Description
DUAL 4-INPUT MULTIPLEXER WITH 3-STATE OUTPUTS
Manufacturer
Motorola
Datasheet

DataSheet
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.
