General Description
The TCA9535 is a 24-pin device that provides 16 bits of general purpose parallel input and output (I/O) expansion for the two-line bidirectional I2C bus or (SMBus) protocol.
The device can operate with a power supply voltage ranging from 1.65 V to 5.5 V.
Key Features
- I2C to Parallel port expander.
- Wide power supply voltage range of 1.65 V to 5V.
- Low standby-current consumption.
- Open-drain active-low interrupt output.
- 5-V tolerant I/O ports.
- 400-kHz Fast I2C bus.
- Polarity inversion register.
- Address by three hardware address pins for use of up to eight devices.
- Latched outputs with high-current drive capability for directly driving LEDs.
- Latch-up performance exceeds 100.
