Abstract
Using a NAND and a NOR gate as input gates provides a simple and efficient input buffer. In the input buffer circuit, a chip select signal is applied in inverted form to the NOR gate and in non-invented form to the NAND gate. The resulting input buffer is both simpler and faster than earlier circuits.
