TISN74AHCT245N
Overview
The SN74AHCT245N is an octal bus transceiver designed for asynchronous two-way communication between data buses. This specific variant belongs to the AHCT family, which features TTL-compatible inputs that allow it to act as a level shifter when interfacing 3.3V logic to 5V systems.
Why Choose This Part
The AHCT family provides a low-power CMOS solution with the benefit of TTL-level input thresholds (VIH of 2V), making it ideal for mixed-voltage systems. Its 20-DIP package is through-hole compatible, which is excellent for prototyping and easy replacement in industrial environments.
Applications
Key Specifications
Getting Started
When designing with this part, ensure the Direction (DIR) and Output Enable (OE) pins are tied to valid logic levels to prevent floating inputs. For breadboard prototyping, place a 0.1uF ceramic decoupling capacitor close to the VCC pin (pin 20) to suppress switching noise.
