Product Details

General description

The PCA9539A is a low-voltage 16-bit General Purpose Input/Output (GPIO) expander with interrupt and reset for I2C-bus/SMBus applications. NXP I/O expanders provide a simple solution when additional I/Os are needed while keeping interconnections to a minimum, for example, in ACPI power switches, sensors, push buttons, LEDs, fan control, etc.

Features and benefits

â–  I2C-bus to parallel port expander
â–  Pin and function compatible with PCA9539
â–  Operating power supply voltage range of 1.65 V to 5.5 V
â–  Low standby current consumption:
♦ 1.5 A (typical at 5 V VDD)
♦ 1.0 A (typical at 3.3 V VDD)
â–  Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs
♦ Vhys = 0.10  VDD (typical)
â–  5 V tolerant I/Os
â–  Active LOW reset input (RESET)
â–  Open-drain active LOW interrupt output (INT)
â–  400 kHz Fast-mode I2C-bus
â–  Internal power-on reset
â–  Power-up with all channels configured as inputs
â–  No glitch on power-up
â–  Latched outputs with 25 mA drive maximum capability for directly driving LEDs
â–  Latch-up performance exceeds 100 mA per JESD78, Class II
â–  ESD protection exceeds JESD22
♦ 2000 V Human Body Model (A114-A)
♦ 1000 V Charged-Device Model (C101)
â–  Packages offered: TSSOP24, HWQFN24
