Description | The PCA9539 provides 16 bits of General Purpose Input/Output (GPIO) expansion with interrupt and reset for I²C-bus/SMBus applications. It is designed for a wide voltage range of 2.3 V to 5.5 V. Nexper... |
Features |
• I²C-bus to parallel port expander • Operating power supply voltage range of 2.3 V to 5.5 V • Ultra low standby current consumption: • 1 µA (maximum) • Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs • Vhys = 0.10 × VCC (typical) • Noise filter on SCL and SDA inputs • 5 V tolerant I/Os • 16 I/O pins which power up configured in input state • Open-drain active LOW interrupt output (INT) • Reset input (RESET) for resetting PCA9539 to default values • 400 kHz Fast-mode I²C-bus • Internal power-on reset • No glitch on power-up • La... |
