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
