PCA9539A

Low voltage 16-bit I2C-bus I/O port with interrupt and reset

Features and benefits

 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

 Low standby current consumption:

 1.5

A (typical at 5 V V

DD)

 1.0

A (typical at 3.3 V V

DD)

 Schmitt-trigger action allows slow input transition and better switching noise immunity

at the SCL and SDA inputs

 Vhys = 0.10  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

 ESD protection exceeds JESD22

 2000 V Human Body Model (A114-A)

 1000 V Charged-Device Model (C101)

 Packages offered: TSSOP24, HWQFN24
