PCAL9555A |
Part Number | PCAL9555A |
Manufacturer | NXP (https://www.nxp.com/) Semiconductors |
Description | The PCAL9555A is a low-voltage 16-bit General Purpose Input/Output (GPIO) expander with interrupt and weak pull-up resistors for I2C-bus/SMBus applications. NXP I/O expanders provide a simple solution... |
Features |
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 A (typical at 5 V VDD) 1.0 A (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 VDD (typical) 5 V tolerant I/Os Open-drain active LOW interrupt output (INT) 400 kHz Fast-mode I2C-bus Internal power-on reset Power-up with all channels configured as inputs and weak pull-up resistors No glitch on power-up Latched outputs with 25 mA drive maximu... |
