The CD74AC245E has a total of 20 pins, which are labeled as follows:
The CD74AC245E is a level shifting and bus transceiver integrated circuit. It facilitates the transfer of data between digital systems operating at different voltage levels. The device features bidirectional data lines, allowing data to flow in both directions. The output enable pins control the direction of data flow.
When the output enable pin is active, data can be transmitted from the A-side to the B-side or vice versa. When the output enable pin is inactive, the data lines are in a high-impedance state, isolating the A-side and B-side.
The CD74AC245E operates by translating the logic levels of the input signals to the corresponding logic levels of the output signals. It ensures that the voltage levels are compatible between the two connected systems, enabling seamless communication.
The CD74AC245E is widely used in various applications where level shifting and bus transceiver functions are required. Some common application areas include:
These alternative models offer similar functionality to the CD74AC245E and can be considered as alternatives based on specific design requirements.
