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)]. Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) TSSOP (24) 7.80 mm × 4.40 mm TCA6416 WQFN (24) 4.00 mm × 4.00 mm B.
•1 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 .
