Product overview
I/O Expander, 16Bit, 400kHz, I2C, SMBus, 2.3V, 5.5V, TSSOP
The PCA 9539PW is a 16 – bit I² C – bus and SMBus low power I / O port with interrupt and reset developed to enhance the NXP Semiconductors family of I² C – bus I / O expanders. The I / O expander provides a simple solution when additional I / O is needed for ACPI power switches, sensors, push buttons Выбор конечного продукта (Output selection), ввод, вывод и регистрация полимеризации (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 or Output register. The polarity of the read register can be inverted with the Polarity inversion register. All registers can be read by the system master. It is identical to the PCA9555 except for the removal of the internal I/O pull-up resistor.
Регистрация Polarity Inversion Register. Active low interrupt output.Active low reset input.Low standby current consumption.Noise filter on SCL/SDA input.No glitch on power-up.Internal power-ON reset.Latch-up testing is done to JEDEC standard JESD78 which exceeds 100mA
