Abstract
An input buffer has input and output inverters. An n-channel transistor is coupled as a source follower between the inverters. The buffer receives a TTL input and provides a CMOS output. The source follower transistor has a large channel width and provides substantial pullup. The output inverter stage can be made larger. A p-channel transistor in parallel with the n-channel source follower transistor permits the internal node to reach a full Vcc level. Another n-channel transistor driven by the input signal permits the node to reach ground.
