This document introduces Fairchild Semiconductor Corporation's AN-966J product, which can achieve 5V/3V level conversion with ultra-high speed and low power consumption.
This document describes the usage of the Fairchild Switch (FST) for 5V to 3V level conversion. The FST is a high-speed, low-power device capable of translating logic levels between 5V and 3V systems. Due to specific voltage drop characteristics when input and supply voltages are at the same level, a diode is recommended to be connected between the 5V power supply and ground to achieve the correct voltage translation.

| Propagation Delay | 250ps |
|---|---|
| Supply Current | 10uA |
| Diode Forward Voltage Drop | 0.7V |
A diode is connected between the 5V power supply and ground to utilize the forward voltage drop.
The voltage at the Vcc pin becomes approximately 4.3V (5V - 0.7V).
