Fonctionnalités et applications

The PCA9517ADP,118 is a part of PCA9517A series I2C-Bus Repeater. It has an operating temperature ranging from -55°C to +85°C and it comes in TSSOP-8 Packaging.

The PCA9517A 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. Using the PCA9517A enables the system designer to isolate two halves of a bus for both voltage and capacitance.

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
  • ESD protection exceeds 5500 V HBM per JESD22-A114, 450 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
  • Packages offered: SO8 and TSSOP8
