General description

The PCA9538A is a low-voltage 8-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 ACPIpower switches, sensors, push buttons, LEDs, fan control, etc.

In addition to providing a flexible set of GPIOs, the wide VDDrange of 1.65 V to 5.5 V allows the PCA9538A to interface with next-generation microprocessors and microcontrollers where supply levels are dropping down to conserve power.

The PCA9538A contains the PCA9538A register set of four 8-bit Configuration, Input, Output, and Polarity Inversion registers.

Features and benefits

? I2C-bus to parallel port expander

? Operating power supply voltage range of 1.65 V to 5.5 V

? Low standby current consumption:

?1.5?A (typical at 5 V VDD)

? 1.0?A (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=0.10?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: TSSOP16 and HVQFN16
