Description
The SV73257C is an ultra-low Ron, low-power, high-
bandwidth, high-speed CMOS/TTL-compatible Quad 2:1
multiplexer/demultiplexer bus switch. It is pin compatible
with industry standard 74F/FCT/LS/AS/ALS257 logic
devices. Its control inputs were not just designed to meet
standard and LV CMOS/TTL logic level, but also
designed to be used with most advanced chipset or SOC
with 1.8V control inputs and outputs. It built in undershoot
clamping diodes on all control inputs and switch inputs
that results in robust and reliable switching.
