General description

The PCA9512 is a hot swappable I2C and SMBus buffer that allows I/O card insertion into a live backplane without corruption of the data and clock buses and includes two dedicated supply voltage pins to provide level shifting between 3.3 V and 5 V systems while maintaining the best noise margin for each voltage level. Either pin may be powered with supply voltages ranging from 2.7 V to 5.5 V with no constraints on which supply voltage is higher. Control circuitry prevents the backplane from being connected to the card until a stop bit or bus idle occurs on the backplane without bus contention on the card. When the connection is made, the PCA9512 provides bi-directional buffering, keeping the backplane and card capacitances isolated.

The dynamic offset design of the PCA9510/11/12/13/14 I/O drivers allow them to be connected to another PCA9510/11/12/13/14 device in series or in parallel and to the A side of the PCA9517. The PCA9510/11/12/13/14 can not connect to the static offset I/Os used on the PCA9515/15A/16/16A/17 B side and PCA9518.

Features

  • Bi-directional buffer for SDA and SCL lines increases fanout and prevents SDA and SCL corruption during live board insertion and removal from multi-point backplane systems
  • Compatible with I2C standard mode, I2C fast mode, and SMBus standards
  • ΔV/Δt rise time accelerators on all SDA and SCL lines with ability to disable ΔV/Δt rise time accelerators through the ACC pin for lightly loaded systems
  • 5 V to 3.3 V level translation with optimum noise margin
  • High-impedance SDA, SCL pins for VCC or VCC2 = 0 V
  • 1 V precharge on all SDA and SCL lines
  • Supports clock stretching and multiple master arbitration/synchronization
  • Operating power supply voltage range: 2.7 V to 5.5 V
  • 5.5 V tolerant I/Os
  • 0 kHz to 400 kHz clock frequency
  • 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 JESDEC Standard JESD78 which exceeds 100 mA
  • Packages offered: SO8, TSSOP8 (MSOP8)
