TCA6408A Low-Voltage 8-BitI2C and SMBus I/O Expander With Interrupt Output, Reset,
and Configuration Registers Features 2 Applications
I2Cto Parallel Port Expander • Servers Operating Power-Supply Voltage Rangeof 1.65V • Routers (Telecom Switching Equipment) 5.5V • Personal Computers Allows Bidirectional Voltage-Level Translation and • Personal Electronics (Gaming Consoles)GPIO Expansion Between 1.8-V, 2.5-V, 3.3-V, • Industrial Automationand 5-VI2C Bus and P-Ports • Products With GPIO-Limited Processors• Low Standby Current Consumptionof1 μA 5-V Tolerant I/O Ports 3 Description 400-kHz FastI2C Bus The TCA6408Aisa 16-pin device that provides 8-bits general purpose parallel input/output (I/O)• Hardware Address Pin Allows Two TCA6408A expansion for the two-line bidirectionalI2C bus (orDeviceson the SameI2 C/SMBus Bus SMBus) protocol. This device can operate witha• Active-Low Reset (RESET) Input power supply voltage ranging from 1.65Vto 5.5Von Open-Drain Active-Low Interrupt (INT) Output both theI2C bus side (VCCI) and on the P-port side
(VCCP). This allows the TCA6408Ato interface with• Input/Output Configuration Register next-generation microprocessors and microcontrollers• Polarity Inversion Register on the SDA/SCL side, where supply levels are• Internal Power-On Reset dropping downto conserve power.In contrastto the
dropping power supplies of microprocessors and• Power Up WithAll Channels Configuredas Inputs
microcontrollers, some PCB components such as• No Glitch On Power Up LEDs remainata 5-V power supply.• Noise Filteron SCL/SDA Inputs
The device supports both 100-kHz (Standard-mode)• Latched Outputs With High-Current Drive and 400-kHz (Fast-mode) clock frequencies. I/OMaximum Capabilityfor Directly Driving LEDs expanders such as the TCA6408A providea simple• Latch-Up Performance Exceeds 100 mA Per solution when additional I/Os are needed forJESD 78, ClassII switches, sensors, push-buttons, LEDs, fans, and so
forth.• Schmitt-Trigger Action Allows Slow Input
