PCAL6408A

Low-voltage translating, 8-bit I2C-bus/SMBus I/O expander

 ESD protection exceeds JESD 22

 2000 V Human-Body Model (A114-A)

 1000 V Charged-Device Model (C101)

 Packages offered: HVQFN16, TSSOP16, XQFN16

2.1 Agile I/O features

 Software backward compatible with PCA6408A with interrupts disabled at power-up

 Pin-to-pin drop-in replacement for PCA6408A

 Output port configuration: bank selectable push-pull or open-drain output stages

 Interrupt status: read-only register identifies the source of an interrupt

 Bit-wise I/O programming features:

 Output drive strength: four programmable drive strengths to reduce rise and fall

times in low-capacitance applications

 Input latch: Input Port register values changes are kept until the Input Port register

is read

 Pull-up/pull-down enable: floating input or pull-up/pull-down resistor enable

 Pull-up/pull-down selection: 100 k

 pull-up/pull-down resistor selection

 Interrupt mask: mask prevents the generation of the interrupt when input changes

state to prevent spurious interrupts
