Pinout
The SN74AHC245PWR has a total of 20 pins. Key pin functions include:
- Pins 2-9 (A1-A8): These are the input/output pins for bus A.
- Pins 11-18 (B1-B8): These are the input/output pins for bus B.
- Pin 1 (DIR): Direction control pin. It determines the direction of data flow; when high, data flows from A to B, and when low, data flows from B to A.
- Pin 19 (OE): Output enable pin. When low, the device is enabled; when high, the outputs are in the high-impedance state.
- Pin 10 (GND): Ground pin.
- Pin 20 (VCC): Supply voltage pin.
This transceiver is widely used for interfacing two bidirectional buses and is well-suited for driving bus lines or buffer memory address registers.
