Product Description

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
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
