I
Operating power supply voltage range of 1.65 V to 5.5 V
Low standby current consumption:
Schmitt-trigger action allows slow input transition and better switching noise immunity
at the SCL and SDA inputs
5 V tolerant I/Os
Open-drain active LOW interrupt output (INT)
400 kHz Fast-mode I
Internal power-on reset
Power-up with all channels configured as inputs with weak pull-up resistors
No glitch on power-up
Latched outputs with 25 mA drive maximum capability for directly driving LEDs
Latch-up performance exceeds 100 mA per JESD78, Class II
ESD protection exceeds JESD22
