The SV73253C is an ultra-low Ron, low-power, high-
bandwidth, high-speed CMOS/TTL-compatible Dual 4:1
multiplexer/demultiplexer bus switch. It is pin compatible
with industry standard 74F253, 74FCT253 and the
74ALS/ALS/LS253 logic devices. It built in undershoot
clamping diodes on all control inputs and switch inputs
that results in robust and reliable switching.
