Texas Instruments TCA6408ARGTR TCA6408ARGTR I/O Expander 8 bit I2C Smbus 1.65 V 5.5 Vqfn 16 Pins
Texas Instruments TCA6408ARGTR TCA6408ARGTR I/O Expander 8 bit I2C Smbus 1.65 V 5.5 Vqfn 16 Pins
The TCA6408ARGTR is an 8-bit I²C and SMBus I/O Expander 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 to 5.5V on both the I²C bus side (VCCI) and on the P-port side (VCCP). 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 5V power supply. The device supports both 100kHz (standard-mode) and 400kHz (fast-mode) clock frequencies. It provides a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans and so forth.
- Active-low reset (RESET)\ input
- Open-drain active-low interrupt (INT)\ output
- Input/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/SDA input
- Latched outputs with high-current drive maximum capability for directly driving LEDs
- Schmitt-trigger action allows slow input transition and better switching noise immunity
- 1µA Low standby current consumption
- 5V Tolerant i/o ports
- 400kHz Fast I²C bus
- Green product and no Sb/Br
