54F 74F253
Dual 4-Input Multiplexer with TRI-STATE Outputs
General Description
The 鈥橣253 is a dual 4-input multiplexer with TRI-STATE
outputs It can select two bits of data from four sources
using common select inputs The output 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
