TCA6416PWR Datasheet PDF - TI

●Description

●This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed to provide general-purpose

●remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL) and serial data (SDA)].

●Features

●• 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 SCL/SDA and 1.8-V, 2.5-V, 3.3-V, or 5-V P Port

●– 2.5-V SCL/SDA and 1.8-V, 2.5-V, 3.3-V, or 5-V P Port

●– 3.3-V SCL/SDA and 1.8-V, 2.5-V, 3.3-V, or 5-V P Port

●– 5-V SCL/SDA and 1.8-V, 2.5-V, 3.3-V, or 5-V P Port

●• I2C to Parallel Port Expander

●• Low Standby Current Consumption of 1 μA

●• Schmitt-Trigger Action Allows Slow Input Transition and Better Switching Noise Immunity at the SCL and SDA Inputs

●– Vhys = 0.18 V Typ at 1.8 V

●– Vhys = 0.25 V Typ at 2.5 V

●– Vhys = 0.33 V Typ at 3.3 V

●– Vhys = 0.5 V Typ at 5 V

●• 5-V Tolerant I/O Ports

●• Active-Low Reset (RESET) Input

●• Open-Drain Active-Low Interrupt (INT) Output

●• 400-kHz Fast I2C Bus

●• 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 Inputs

●• Latched Outputs With High-Current Drive Maximum Capability for Directly Driving LEDs

●• Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II

●• ESD Protection Exceeds JESD 22

●– 2000-V Human-Body Model (A114-A)

●– 200-V Machine Model (A115-A)

●– 1000-V Charged-Device Model (C101)
