A 3V - 5V level shifter, which accepts voltages on the "IN" port in the range of 2.7V < VCCA < 3.6V, and is designed to produce voltages on the "OUT" port in the range of 4.5V < VCCB < 5.5V, will be discussed and is shown in Figure 1.1. The invention is designed for interfacing circuitry operating at two different voltages. It is necessary to have the capability to interface circuitry operating at two different voltages to integrate the lower voltage technologies into the mainstream integrated circuit sales.
