The SN74LVTH245APW has a total of 20 pins, which are assigned as follows:
The SN74LVTH245APW is designed to translate signals between two different voltage levels, typically between a microcontroller or processor and other peripheral devices. It utilizes a combination of input/output buffers and control circuitry to achieve bi-directional voltage level translation. The DIR pin controls the direction of data flow, while the OE pins enable/disable the outputs. When the OE pins are active, the device drives the bus with the translated signals. When the OE pins are inactive, the outputs enter a high impedance state, allowing other devices to drive the bus.
The SN74LVTH245APW is commonly used in various applications, including:
These alternative models provide options based on specific requirements, such as voltage range, power consumption, and logic family compatibility.
In conclusion, the SN74LVTH245APW is a versatile level shifter/transceiver IC that enables bi-directional voltage level translation between different logic levels. Its high-speed operation, tri-state outputs, and wide supply voltage range make it suitable for various applications
