General Description
IDTQS3251 General Description
The QS3251 is a high-speed CMOS TTL-compatible 8:1 multiplexer/demultiplexer. The QS3251 has 3-state outputs. The QS3251 is a function and pinout compatible version of the 74F251, 74FCT251 and the 74ALS/AS/LS251 8:1 multiplexers. The low ON resistance of the QS3251 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise.
Mux/Demux devices provide an order of magnitude faster speed than equivalent logic devices.
The QS3251 is characterized for operation at -40°C to +85°C.
