Abstract
A novel sense amplifier circuit providing conversion of MOS input signals to TTL output signals with tri-state logic output at the output data bus, the input circuit of the sense amplifier providing current sensing and programmable input thresholds for economical construction and enhanced speed of operation of the sense amplifier. A novel tri-state operation is provided for the input section of the sense amplifier to provide either a clamped voltage at the input data bus line during MOS to TTL communication or a floating input when it is desired that MOS devices on the input data bus are to communicate.
