Fonctionnalités et applications
The PCA9517AD,118 is a Part of PCA9517A Series 5.5 V Level Translating I2C-Bus Repeater. Operating temperature ranges between -40°C to 85°C and is available in SOIC-8 Package.

It is a CMOS integrated circuit that provides level shifting between low voltage (down to 0.9 V) and higher voltage (2.7 V to 5.5 V) I2C-bus or SMBus applications. While retaining all the operating modes and features of the I2C-bus system during the level shifts, it also permits extension of the I2C-bus by providing bidirectional buffering for both the data (SDA) and the clock (SCL) lines, thus enabling two buses of 400 pF.

Features:

  • 2 channel, bidirectional buffer isolates capacitance and allows 400 pF on either side of the device
  • Voltage level translation from 0.9 V to 5.5 V and from 2.7 V to 5.5 V
  • Footprint and functional replacement for PCA9515/15A
  • 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-bus devices and multiple masters
  • Powered-off high-impedance I2C-bus pins
  • Port A operating supply voltage range of 0.9 V to 5.5 V
  • Port B operating supply voltage range of 2.7 V to 5.5 V
  • 5 V tolerant I2C-bus and enable pins
  • 0 Hz to 400 kHz clock frequency (the maximum system operating frequency may be
  • less than 400 kHz because of the delays added by the repeater)
  • ESD protection exceeds 5500 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101
  • Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
  • Packages offered: SO8, TSSOP8 and HWSON8
