TCA6408A Low-Voltage 8-BitI2C and SMBus I/O Expander With Interrupt Output, Reset,
and Configuration Registers Features 2 ApplicationsI2Cto 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
