2000 V Human-Body Model (A114-A)
1000 V Charged-Device Model (C101)
Packages offered: TSSOP24, HWQFN24, UFBGA24, VFBGA24, XFBGA24
2.1 Agile I/O features
Software backward compatible with PCA6416A with interrupts disabled at power-up
Pin-to-pin drop-in replacement with PCA6416A
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
