Description
The SN74AHCT245DWR operates with a wide power supply range from 4.5V to 5.5V, making it suitable for systems requiring 5V logic levels. It offers high noise immunity and can drive up to 24mA at each output, providing robust performance for interfacing different parts of a system. The transceiver is also designed for low power consumption.
Packaged in a 20-pin SOIC (DWR) configuration, it is suitable for automatic insertion in printed circuit boards. This device is typically used in applications requiring isolation between data buses, such as in memory interfacing, and for buffering and driving data lines in microprocessor systems.

Pinout
Key pin functions include:
- A and B Ports (A0-A7, B0-B7): These are the data input/output ports, with A0-A7 as one bus and B0-B7 as the other, allowing for 8-bit data transfer.
- Direction (DIR) Pin: This pin controls the direction of data flow. When DIR is high, data flows from A to B; when low, data flows from B to A.
- Output Enable (OE) Pin: This pin is used to enable or disable the outputs. When OE is low, the outputs are enabled; when high, the outputs are in a high-impedance state.
- Power Supply (VCC) and Ground (GND): These pins provide the necessary power to the device.
This device is useful in applications requiring level shifting and buffer interfacing between processors and peripheral devices.
