Table 1. PIN DESCRIPTION

Description

GND

Ground

VREF1

Low−voltage side reference supply voltage for SCL1 and SDA1

SCL1

Serial clock, low−voltage side; connect to VREF1 through a pull−up resistor

SDA1

Serial data, low−voltage side; connect to VREF1 through a pull−up resistor

SDA2

Serial data, high−voltage side; connect to VREF2 through a pull−up resistor

SCL2

Serial clock, high−voltage side; connect to VREF2 through a pull−up resistor

VREF2

High−voltage side reference supply voltage for SCL2 and SDA2

Switch enable input; connect to VREF2 and pull−up through a high resistor

Table 2. FUNCTION TABLE

Input EN (Note 1)

Function

Low

Disconnect

High

SCL1 = SCL2; SDA1 = SDA2

1. EN is controlled by the Vbias(ref)(2) logic levels and should be at least 1 V higher than Vref(1) for best translator operation.
