Package

The SN74AC245PWR is packaged in a TSSOP (Thin Shrink Small Outline Package) with a 20-pin configuration.

Pinout

The SN74AC245PWR is an octal bus transceiver with 3-state outputs, featuring a total of 20 pins. Its primary functions include bidirectional data transmission and buffering between different bus systems.
The pin configuration consists of:
- A1-A8: Data inputs for one direction of the bus.
- B1-B8: Data outputs for the opposite direction of the bus.
- DIR: Direction control input, determining the data flow (A to B or B to A).
- OE: Output enable input, which disables the outputs when low, putting them in a high-impedance state.
- GND: Ground connection.
- VCC: Power supply connection.
The device operates at a wide voltage range and is suitable for level shifting between different logic levels, providing high-speed data transfer for a variety of applications.
