Working Principles

The SN74CBT3245CRGYR is a bidirectional voltage-level translator designed to facilitate communication between digital systems operating at different voltage levels. It uses a combination of CMOS and BiCMOS technology to achieve high-speed operation with low power consumption.

The device consists of eight bidirectional channels, each capable of translating signals between two voltage domains. The channel selection inputs (A0-A2 and B0-B7) determine the direction of translation for each channel. When the output enable (OE) pin is low, the device is enabled, allowing bidirectional data transfer. Conversely, when OE is high, the device is disabled, isolating the input and
