DESCRIPTION:
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.
equivalent logic devices.
The QS3251 is a high-speed CMOS TTL-compatible 8:1 multiplexer/
Mux/Demux devices provide an order of magnitude faster speed than
The QS3251 is characterized for operation at -40°C to +85°C.
