Product Summary

The PCA9515AD is a BiCMOS integrated circuit intended for I2C bus and SMBus systems applications. The PCA9515AD contains two identical bidirectional open-drain buffer circuits that enable I2C and similar bus systems to be extended without degradation of system performance. The PCA9515AD also can be used to run two buses:one at5-V interface levels and the other at 3.3-V interface levels, or one at 400-kHz operating frequency and the other at 100-kHz operating frequency.

Parametrics

PCA9515AD absolute maximum ratings: (1) Supply voltage range Vcc: -0.5 to 7V; (2) Enable input voltage range VI: -0.5 to 7V; (3) I2C bus voltage range: -0.5 to 7V; (4) Input clamp current IIK: -50mA (VI<0) ; (5) Output clamp current: -50mA (VO<0) ; (6) Continuous output current: ±50mA; (7) Continuouscurrentthrough VCC or GND: ±100mA; (8) Storagetemperature range: -65 to 150° C.
