Product Summary

The PCA9534D is a 16-pin CMOS device that provides 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. The improvements of PCA9534D 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, etc.

Parametrics

PCA9534D absolute maximum ratings: (1)supply voltage: -0.5 to +6.0 V; (2)input current: ±20 mA; (3)voltage on an input/output pin VSS: - 0.5 to 5.5 V; (4)output current on pin IOn: ±50 mA; (5)supply current: 85 mA; (6)ground supply current: 100 mA; (7)total power dissipation: 200 mW; (8)storage temperature: -65 to +150 ℃; (9)ambient temperature: -40 to +85 ℃.
