General description
The PCA9554B and PCA9554C are low-voltage 8-bit General Purpose Input/Output (GPIO) expanders with interrupt for I2C-bus/SMBus applications. The only difference between the PCA9554B and PCA9554C is their I2C fixed address allowing a larger number of the same device on the I2C-bus with no chance of address conflict. 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
■ 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 μA (typical at 5 V VDD)
◆ 1.0 μA (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 x VDD (typical)
■ 5 V tolerant I/Os
■ Open-drain active LOW interrupt output (INT)
■ 400 kHz Fast-mode I2C-bus
■ Input/output configuration register
■ Polarity inversion register
■ 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
