DESCRIPTION

The PCA9515 is a BiCMOS integrated circuit intended for application in I2C and SMBus systems.

While retaining all the operating modes and features of the I2C system it permits extension of the I2C-bus by buffering both the data (SDA) and the clock (SCL) lines, thus enabling two buses of 400 pF.

FEATURES

• 2 channel, bi-directional buffer

• I2C-bus and SMBus compatible

• Active-HIGH repeater enable input

• Open-drain input/outputs

• Lock-up free operation

• Supports arbitration and clock stretching across the repeater

• Accommodates standard mode and fast mode I2C devices and multiple masters

• Powered-off high impedance I2C pins

• Operating supply voltage range of 3.0 V to 3.6 V

• 5.5 V tolerant I2C and enable pins

• 0 to 400 kHz clock frequency1

• ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101.

• Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA.

• Package offerings: SO and TSSOP
