BL3257 Datasheet, PDF (1/7 Pages) SHANGHAI BELLING CO., LTD. – Low On-Resistance

4 Channel 2:1 Switch BL3257
BL3257
Description
BL3257 is a quad single pole/double
throw high-speed CMOS TTL-compatible
bus switch. The low on resistance of the
switch allows inputs to be connected to
outputs without adding propagation delay
or generating additional ground bounce
noise. Also this device has exceptionally
high current capability, which is far
greater than most analog switches
offered today. A single 5V supply is all
that is required for operation.
