DESCRIPTION
The AS4420 and AS4429 family operate over 4.5V to 18V,
can withstand high current peaking of 6A and have matched
rise and fall times under 25ns. The product has been
designed utilizing Calogic’s rugged CMOS process with
protection for latch up and ESD. The product is available in
inverting (AS4429) and noninverting (AS4420) configurations.
