Product Overview

The PCA9514ADP is a hot swappable I²C-bus and SMBus buffers that allow I/O card insertion into a live backplane without corrupting the data and clock buses. Control circuitry prevents the backplane from being connected to the card until a stop command or bus idle occurs on the backplane without bus contention on the card. When the connection is made, it provides bidirectional buffering, keeping the backplane and card capacitances isolated. Rise time accelerator circuitry allows the use of weaker DC pull-up currents while still meeting rise time requirements. It incorporates a digital ENABLE input pin, which enables the device when asserted HIGH and forces the device into a Low current mode when asserted LOW and an open-drain READY output pin, which indicates that the backplane and card sides are connected together or not. The rise time accelerator threshold is 0.8V to provide better noise margin over the PCA9511A which is set to 0.6V.
  • Compatible with I²C-bus Standard-mode, I²C-bus Fast-mode and SMBus standards
  • Active HIGH ENABLE input
  • Active HIGH READY open-drain output
  • Supporting clock stretching and multiple master arbitration/synchronization
  • Built-in ∆V/∆t rise time accelerators
  • Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100mA
  • 0Hz to 400kHz Clock frequency
  • Rise time accelerator threshold moved from 0.6 to 0.8V for improved noise margin

Applications

Industrial, Automation & Process Control, Signal Processing, Clock & Timing, Consumer Electronics, Communications & Networking
