8 Detailed Description

8.1 Overview

The SN74LVC2G07 device contains two open drain buffer with a maximum sink current of 32 mA. This device is

damaging current backflow through the device when it is powered down.

8.3 Feature Description

The open-drain configuration means that the device cannot provide its own output drive current; instead, it relies

on pullup resistors to provide the "high" bus state. It can only drive the bus low. In the "Hi-Z" state, the

SN74LVC2G07 acts as an open circuit and allows the external pullup to pull the bus high. Therefore, the pullup

voltage determines the output level and therefore the SN74LVC2g07 can be used for up or down-translation. The
