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
I/Os with integrated dynamic pull-down resistors
help reduce external component count
Control inputs with integrated static pull-down resistors
allow for floating control inputs
High drive strength (up to 32 mA at 5 V)
Low power consumption:
4-µA maximum (25°C)
12-µA maximum (–40°C to 125°C)

)
feature:
If either V
CC
supply is < 100 mV or disconnected, all I/Os get pulled-down and then become high-impedance
I

supports partial-power-down mode operation
Compatible with LVC family level shifters
Control logic (DIR and
OE
) are referenced to V
CCA
Operating temperature from –40°C to +125°C
Latch-up performance exceeds 100 mA per JESD 78, Class II
ESD protection exceeds JESD 22
