Product Description

The TCA6408A is a 16-pin device that provides 8-bits of general purpose parallel input/output (I/O) expansion for the two-line bidirectional I²C bus (or SMBus) protocol. This device can operate with a power supply voltage ranging from 1.65 V to 5.5 V on both the I²C bus side (V_CCI) and on the P-port side (V_CCP). This allows the TCA6408A to interface with next-generation microprocessors and microcontrollers on the SDA/SCL side, where supply levels are dropping down to conserve power. In contrast to the dropping power supplies of microprocessors and microcontrollers, some PCB components such as LEDs remain at a 5-V power supply.

The device supports both 100-kHz (Standard-mode) and 400-kHz (Fast-mode) clock frequencies. I/O expanders such as the TCA6408A provide a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans, and so forth.

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 1 µA
5-V Tolerant I/O ports
400-kHz Fast I²C bus
Hardware address pin allows two TCA6408A 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 exceeds 100 mA Per JESD 78, class II
