Features
AEC-Q100 qualified for automotive applications
Fully configurable dual-rail design allows each port to operate from 1.1 V to 5.5 V
Robust, glitch-free power supply sequencing
Up to 420-Mbps support for 3.3 V to 5.0 V
Schmitt-trigger inputs allow for slow or noisy inputs
Input with integrated dynamic pull-down resistors
help reduce external component count
High drive strength (up to 32 mA at 5 V)
Low power consumption
3-µA maximum (25°C)

feature
If either V
CC
supply is < 100 mV or disconnected, all I/O's get pulled-down and then become high-impedance
Overvoltage tolerant inputs accept voltages up to 5.5 V regardless of supply voltage.
I

supports partial-power-down mode operation
Operating temperature from –40°C to +125°C
Latch-up performance exceeds 100 mA per JESD 78, class II
ESD protection exceeds JESD 22
