Features

Key Features

  • I²C-bus to parallel port expander
  • Pin and function compatible with PCA9539
  • Operating power supply voltage range of 1.65 V to 5.5 V
  • Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs
  • Vhys = 0.10 x VDD (typical)
  • 5 V tolerant I/Os
  • Active LOW reset input (RESET)
  • Open-drain active LOW interrupt output (INT)
  • 400 kHz Fast-mode I²C-bus
  • Internal power-on reset
  • Power-up with all channels configured as inputs
  • No glitch on power-up
  • Latched outputs with 25 mA drive maximum capability for directly driving LEDs
  • Latch-up performance exceeds 100 mA per JESD78, Class II
  • Packages offered: TSSOP24, HWQFN24

Low Standby Current Consumption

  • 1.5 μA (typical at 5 V VDD)
  • 1.0 μA (typical at 3.3 V VDD)

ESD Protection Exceeds JESD22

  • 2000 V Human Body Model (A114-A)
  • 1000 V Charged-Device Model (C101)
