Title: A level converter
Inventor: PARK YONG-BO
IPC: H03K19/017
Filed: 1990-02-27
Abstract: A level converter for converting a TTL level input signal to a CMOS level comprises a NOR gate circuit (1) provided with the TTL signal, inverter (INV) connected to the NOR gate circuit, and a speed control circuit (2). The usual configuration converter (1 of Fig. 2) is slow to response to a change of TTL input from high to low as PMOS transistor PI2 is smaller than CMOS transistor NI2. A fast conversion speed is obtained by turning on both PMOS transistors (PI2, PI4) when the TTL signal goes from high to low. Transistor PI4 is coupled to the output of circuit C1 via transistor PI3. When the TTL input goes low transistor PI4 is turned on to take VNOR high relatively quickly. As PI4 is turned off by the constant voltage circuit 4, VNOR stays high as the NOR gate circuit 1 now outputs a high signal. <IMAGE>
