PCA9554APW | 8-bit I2C-bus and SMBus I/O port with interrupt; • Operating power supply voltage range of 2.3 V to 5.5 V\n• 5 V tolerant I/Os\n• Polarity Inversion register\n• Active LOW interrupt output\n• Low standby current\n• Noise filter on SCL/SDA inputs\n• No glitch on power-up\n• Internal power-on reset\n• 8 I/O pins which default to 8 inputs\n• 0 Hz to 400 kHz clock frequency\n• ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM perJESD22-C101\n• Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA\n• AEC-Q100 compliance available\n• Packages offered: DIP16, SO16, SSOP16, SSOP20, TSSOP16, HVQFN16 (2 versions: 4 mm x 4 mm x 0.85 mm and 3 mm x 3 mm x 0.85 mm), and bare die\n; 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.\nThe PCA9554/PCA9554A consist of an 8-bit Configuration register (Input or Output selection); 8-bit Input Port register, 8-bit Output Port register and an 8-bit Polarity Inversion register (active HIGH or active LOW operation). The system master 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. All registers can be read by the system master. Although pin-to-pin and I2C-bus address compatible with the PCF8574 series, software changes are required due to the enhancements and are discussed in Application Note AN469.\nThe PCA9554/PCA9554A open-drain interrupt output is activated when any input state differs from its corresponding Input Port register state and is used to indicate to the system master that an input state has changed. The power-on reset sets the registers to their default values and initializes the device state machine.\nThree hardware pins (A0, A1, A2) vary the fixed I2C-bus address and allow up to eight devices to share the same I2C-bus/SMBus. The PCA9554A is identical to the PCA9554 except that the fixed I2C-bus address is different allowing up to sixteen of these devices (eight of each) on the same I2C-bus/SMBus.\n | 恩XP | 恩XP | |
