Visão Geral
Description
Key features include:
- Bidirectional Data Flow: It can transmit data in both directions, controlled by a direction pin (DIR).
- 3-State Outputs: When the output enable pin (OE) is active, the outputs are in a high-impedance state, effectively disconnecting the bus.
- Wide Voltage Range: Operates typically from 2V to 6V.
- High-Speed Performance: Suitable for high-speed applications due to its fast switching characteristics.
The 74HC245PW is commonly used in applications where data needs to be isolated or transferred between microprocessors, microcontrollers, and memory systems, ensuring data integrity and minimizing bus loading. Its compact TSSOP (Thin Shrink Small Outline Package) makes it suitable for space-constrained designs.

Pinout
Here is a concise pin description:
- Pins 1, 10, 19: GND (Ground)
- Pin 20: VCC (Positive Supply Voltage)
- Pin 1: DIR (Direction Control)
- Pin 19: OE (Output Enable)
- Pins 2-9: A0-A7 (Data Bus A)
- Pins 11-18: B0-B7 (Data Bus B)
The 74HC245PW is often used in digital systems for bus interfacing, enabling data transfer and isolation between two buses, and is suitable for applications requiring low power consumption and high-speed operation.
