具有三态输出的高速 CMOS 逻辑 8 输入多路复用器
The HC251 and HCT251 are 8-channel digital multiplexers 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 output enable 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 inputs 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.
