Pinout
Here are the key functions of the pins:
- Pins 2-9 (A1-A8): Data inputs/outputs on the A side.
- Pins 11-18 (B1-B8): Data inputs/outputs on the B side.
- Pin 1 (DIR): Direction control pin. It determines the direction of data flow. When high, data is transferred from A to B; when low, from B to A.
- Pin 19 (OE): Output enable pin. When low, the transceiver is active. When high, the outputs are in a high-impedance state.
- Pin 10 (GND): Ground.
- Pin 20 (VCC): Supply voltage.
This device is typically used in applications where buffering and isolation of data buses are needed. It supports high-speed data transfer and is compatible with TTL logic levels.
