Description
General description
The PCA9554 and PCA9554A are 16-pin CMOS devices that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and were developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders.
The improvements include higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O configuration, 400 kHz clock frequency, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, and so on.
Features and benefits
• Operating power supply voltage range of 2.3 V to 5.5 V
• 5 V tolerant I/Os
• Polarity Inversion register
• Active LOW interrupt output
• Low standby current
• Noise filter on SCL/SDA inputs
• No glitch on power-up
• Internal power-on reset
• 8 I/O pins which default to 8 inputs
• 0 Hz to 400 kHz clock frequency
• ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101
• Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
• AEC-Q100 compliance available
• Packages offered: SO16, SSOP16, SSOP20, TSSOP16, HVQFN16 (2 versions: 4 x 4 x 0.85 mm and 3 x 3 x 0.85 mm), and bare die
Alternatives

Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
