PCA9510D: Hot swappable I²C-bus and SMBus bus buffer ARCHIVED

Overview

The PCA9510 is a hot swappable I2C-bus and SMBus buffer that allows 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, the PCA9510 provides bidirectional buffering, keeping the backplane and card capacitances isolated.

Features

Bidirectional 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-bus Standard-mode, I2C-bus Fast-mode, and SMBus standards
Active HIGH ENABLE input
Active HIGH READY open-drain output
High-impedance SDA and SCL pins for VCC = 0 V
1 V precharge on all SDA and SCL lines (IN only)
Supports clock stretching and multiple controller arbitration/synchronization
Operating power supply voltage range: 2.7 V to 5.5 V
5.5 V tolerant I/Os
0 Hz 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 JEDEC Standard JESD78 which exceeds 100 mA
Packages offered: SO8, TSSOP8 (MSOP8)
