Product Overview
PCA9554ADB,118 is an 8bit I²C-bus and SMBus I/O port with interrupt CMOS device. It provides 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, 5V I/O tolerance, lower supply current, individual I/O configuration, 400KHz 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. The system can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding input port or output port register. The polarity of the read register can be inverted with the Polarity inversion register.
- 5V 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
- 0Hz to 400KHz clock frequency range
- ESD protection exceeds 2000V HBM per JESD22-A114 and 1000V CDM per JESD22-C101
- Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100mA
- Supply voltage range from 2.3 to 5.5V (VSS = 0V, Tamb = -40°C to +85°C)
- Supply current is 104µA typ (VSS = 0V, Tamb = -40°C to +85°C)
- Power-on reset voltage is 1.7V typ (no load; VI = VDD or VSS, Tamb = -40°C to +85°C)
- SSOP16 package, ambient temperature range from -40 to +85°C
