Working Principles
The 74ABTH162460DLRG4 is a bidirectional voltage level translator that allows seamless communication between two different voltage domains. It utilizes a combination of level-shifting circuitry and automatic direction control to ensure proper signal translation.
When the Output Enable (OE1) pin is high, the IC is enabled, and the direction of data flow is determined by the voltage levels on the A1-A14 and B1-B14 pins. If the voltage on the A-side is higher than the B-side, the data is translated from A to B, and vice versa.
The IC operates with LVTTL/LVCMOS input voltage levels on the A-side and provides LVCMOS output voltage levels on the B-side. The Schmitt-trigger inputs help in reducing noise sensitivity and provide reliable operation.
