- Documentation available to aid functional safety system design
I²C to parallel port expander
Operating power-supply voltage range of 1.65 V to 3.6 V
Allows bidirectional voltage-level translation and GPIO expansion between 1.8-, 2.5-, and 3.3-V I²C bus and P-ports
Low standby current consumption
400-kHz Fast I²C Bus
Hardware address pin allows Two TCA6408A-Q1 devices on the same I²C/SMBus bus
Active-low reset ( RESET) input
Open-drain active-low interrupt ( INT) output
Input and output configuration register
Polarity inversion register
Internal power-on reset
Power up with all channels configured as inputs
No glitch on power up
Noise filter on SCL and SDA inputs
Latched outputs with high-current drive maximum capability for directly driving LEDs
Latch-up performance meets 100 mA per AEC Q100-004
Schmitt-Trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs
