Renesas Electronics QS3257QG8 Multiplexer/Demultiplexer, Demultiplexer, Multiplexer, 16-Pin QSOP

The Renesas Electronics high speed CMOS LVTTL compatible quad 2:1 multiplexer or demultiplexer. The QS3257 is a function and pinout compatible quick switch version of the quad 2:1 multiplexers. The low on resistance of the allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise.

Enhanced n channel fet with no inherent diode to vcc
Five ohm bidirectional switches connect inputs to outputs
Zero propagation delay, zero ground bounce
Undershoot clamp diodes on all switch and control inputs
