74AC253 鈥?74ACT253
Dual 4-Input Multiplexer with 3-STATE Outputs
General Description
The AC/ACT253 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 individu-
ally 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.
