Overview

The MC74VHCT50ADTR2G is a high-speed CMOS non-inverting hex buffer designed for operation from 2V to 5.5V. It features TTL-compatible inputs and CMOS-compatible outputs, making it an ideal choice for level shifting in mixed-voltage systems. The device provides six independent channels in a compact 14-TSSOP package with integrated power-down protection on both inputs and outputs.

Why Choose This Part

This buffer offers the speed performance of equivalent bipolar Schottky TTL while maintaining the low power consumption of CMOS. Its wide supply range of 2V to 5.5V and 5V-tolerant inputs allow it to interface safely between different voltage domains without the need for external clamping diodes.

Applications

Voltage Level Shifting
Translating 3.3V TTL logic levels to 5V CMOS logic levels in mixed-voltage digital systems.
Signal Buffering
Providing high-current drive capability (up to 8mA) for long PCB traces or high-fanout clock distribution.
Output Isolation
Utilizing power-down protection to isolate sensitive logic stages when the supply voltage is removed.

Getting Started

To use this device, ensure pin 14 (VCC) is decoupled with a 0.1uF ceramic capacitor placed close to the package. The 14-TSSOP package has a 0.65mm lead pitch, requiring standard SMT reflow processes. Connect unused inputs to VCC or GND to prevent oscillations and excessive quiescent current.
