Working Principles

The 74CBTLV3244DS,118 is a bidirectional voltage level translator designed to facilitate communication between two buses operating at different voltage levels. It utilizes CMOS technology to achieve fast switching speeds while maintaining low power consumption.

The IC features four independent bidirectional channels, each capable of translating signals between two voltage domains. The direction of translation is controlled by the Output Enable (OE#) pin. When OE# is low, the IC is active and performs level shifting, allowing data transmission between the A and B ports. When OE# is high, the IC is in a high-impedance state, isolating the buses.
