Features

Key Features

  • I²C-bus to parallel port expander
  • 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 Port P
    • 2.5 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P
    • 3.3 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P
    • 5 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P
  • Low standby current consumption:
    • 1.5 μA typical at 5 V VDD
    • 1.0 μA typical at 3.3 V VDD
  • Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs:
    • Vhys = 0.18 V (typical) at 1.8 V
    • Vhys = 0.25 V (typical) at 2.5 V
    • Vhys = 0.33 V (typical) at 3.3 V
    • Vhys = 0.5 V (typical) at 5 V
  • 5 V tolerant I/O ports
  • Active LOW reset input (RESET)
  • Open-drain active LOW interrupt output (INT)
  • 400 kHz Fast-mode 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 25 mA 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)
    • 1000 V Charged-Device Model (C101)
  • Packages offered: TSSOP24, HWQFN24, VFBGA24

This bus is called the Inter-IC or I2C-bus. Only two bus lines are required: a serial data line (SDA) and a serial clock line (SCL). Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 kbit/s in the Standard-mode, up to 400 kbit/s in the Fast-mode, up to 1 Mbit/s in the Fast-mode Plus (Fm+), or up to 3.4 Mbit/s in the High-speed mode. 1442125286808710770774 PSP 751.0 KB None None documents None 1442125286808710770774 /docs/en/user-guide/UM10204.pdf 750958 /docs/en/user-guide/UM10204.pdf UM10204 documents N N 2016-07-12 I2C-bus specification and user manual /docs/en/user-guide/UM10204.pdf /docs/en/user-guide/UM10204.pdf User Guide N 132339537837198660 2024-10-24 pdf N en Oct 1, 2021 132339537837198660 User Guide Y N I2C-bus specification and user manual Package Information Package Information 3 3 1.1 English 1455079215079728313090 PSP 215.4 KB None None documents None 1455079215079728313090 /docs/en/package-information/SOT994-1.pdf 215444 /docs/en/package-information/SOT994-1.pdf SOT994-1 documents N N 2019-09-26 plastic thermal enhanced very very thin quad flat package;
