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 and 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
Packages offered: TSSOP24, HVQFN24
Pin to pin replacement for PCA9555 and PCA9555A with interrupts disabled at
power-up
Output port configuration: bank selectable push-pull or open-drain output stages
Interrupt status: read-only register identifies the source of an interrupt

Output drive strength: four programmable drive strengths to reduce rise and fall
Input latch: Input Port register values changes are kept until the Input Port register
Pull-up/pull-down enable: floating input or pull-up/down resistor enable
Pull-up/pull-down selection: 100 k pull-up/down resistor selection
Interrupt mask: mask prevents the generation of the interrupt when input changes
