Texas Instruments SN74ACT16245QDLREP's Pinouts
Power and Ground Pins:
VCC: This pin is connected to the power supply, which typically operates in the range of 4.5V to 5.5V. It provides the necessary electrical power for the device to function.
GND: The ground pin serves as the electrical reference point for the chip. It is connected to the ground plane of the circuit board to complete the electrical circuit.
- Data Pins:
A0 - A7: These are the input/output pins for data bus A. They can be used to transmit or receive data depending on the direction control.
B0 - B7: These are the input/output pins for data bus B, similar to A0 - A7, but for the other data bus.
Control Pins:
DIR: The direction control pin. When this pin is high, data is transferred from bus A to bus B (A→B). When it is low, data is transferred from bus B to bus A (B→A).
G: The output enable/disable pin. When this pin is low, the outputs are enabled, allowing data to be transferred between the buses. When it is high, the outputs are in a high - impedance state, effectively isolating the buses from each other.
