Working Principles

The SN74LVTH16374GRDR is designed to shift logic levels between different voltage domains. It consists of 16 D-type flip-flops with 3-state outputs. The inputs are latched on the rising edge of the clock signal, and the output states can be controlled by the output enable (OE) pin.

When the OE pin is high, the outputs are in the high-impedance state, allowing other devices to drive the shared bus. When the OE pin is low, the outputs reflect the stored data from the inputs.

The IC operates within a specified supply voltage range and provides reliable level shifting while maintaining high-speed performance.

Detailed Application Field Plans

1. Microcontrollers and microprocessors: Interface between different voltage domains in embedded systems.
2. Communication systems: Level shifting between different logic families (e.g., TTL and CMOS) in serial communication interfaces.
3. Data acquisition systems: Conversion of analog signals to digital levels using ADCs and subsequent level shifting for processing.
4. Industrial automation: Interfacing between different control modules operating at different voltage levels.
5. Automotive electronics: Level shifting in automotive communication protocols such as CAN or LIN buses.
