Zero propagation delay, zero ground bounce
Undershoot clamp diodes on all switch and control inputs
TTL-compatible control inputs
Available in SOIC, QSOP, and S1 packages
IDTQS3257
DESCRIPTION:
The QS3257 is a high-speed CMOS LVTTL-compatible Quad 2:1
multiplexer/demultiplexer. The QS3257 is a function and pinout compatible
QuickSwitch version of the 74F257, 74FCT257, and the 74ALS/AS/LS257
Quad 2:1 multiplexers. The low ON resistance of the QS3257 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 QS3257 is characterized for operation at -40擄C to +85擄C.
