CD74HCT251E

IC, LOGIC, 74HCT, MULTIPLEXER.

The CD74HCT251E is a 8-input high speed CMOS Multiplexer with three-state outputs, fabricated with high-speed silicon-gate CMOS technology. Together with the low power consumption of standard CMOS integrated circuits, they possess the ability to drive 10 LSTTL loads. The three-state feature makes them ideally suited for interfacing with bus lines in a bus-oriented system. This multiplexer features both true (Y) and complement (Y\) outputs as well as an OE\ input. The OE\ must be at a low logic level to enable this device. When the OE\ input is high, both outputs are in the high-impedance state. When enabled, address information on the data select input determines which data input is routed to the Y and Y\ outputs. The HCT251 logic family is speed, function and pin-compatible with the standard LS251.
