TECHNICAL DATA

KK74ACT251

8-Input Data Selector/Multiplexer

with 3-State Outputs

High-Speed Silicon-Gate CMOS

The KK74ACT251 is identical in pinout to the LS/ALS251,

HC/HCT251. The KK74ACT251 may be used as a level converter for

interfacing TTL or NMOS outputs to High Speed CMOS inputs.

The device selects one of the eight binary Data Inputs, as determined

by the Address Inputs. The Output Enable pin must be at a low level for

the selected data to appear at the outputs. If Output Enable is high, the Y

and the Y outputs are in the high-impedance state. This 3-State feature

allows the KK74ACT251 to be used in bus-oriented systems.
