Product Introduction
The TCA6416A is a 24-pin device that provides 16- bits of general purpose parallel input/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 on the I²C bus side (VCCI) and a power supply voltage ranging from 1.65 V to 5.5 V on the P-port side (VCCP).
The device supports both 100-kHz (Standard-mode) and 400-kHz (Fast-mode) clock frequencies. I/O expanders such as the TCA6416A provide a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans, etc.
Features
- I²C to Parallel Port Expander Operating Power-Supply Voltage Range of 1.65 V to 5.5 V Allows Bidirectional Voltage-Level Translation and GPIO Expansion Between 1.8-V, 2.5-V, 3.3-V, and 5-V I²C Bus and P-Ports
- Low Standby Current Consumption of 3 μA
- 5-V Tolerant I/O Ports
- 400-kHz Fast I²C Bus
- Hardware Address Pin Allows Two TCA6416A Devices on the Same I²C/SMBus Bus
- Active-Low Reset Input (RESET)
- Open-Drain Active-Low Interrupt Output (INT)
- Input/Output Configuration Register
- Polarity Inversion Register
- Internal Power-On Reset
