Abstract
An input buffer capable of high voltage operation includes a transmission gate connected to a boosting voltage source. The input buffer can be used to maintain the processing speed and noise margin of a digital circuit even through the input voltage thereof is excessively high. Moreover, the input buffer can be used in an address latch or inverter-type circuit.
Claims9
An input buffering means for high voltage operation, comprising:
- an input buffer having a transmission gate and at least one resistor arranged to function as an input terminal of said input buffering means, a gate of said transmission gate being connected to a boosting voltage source;
- a control latch circuit connected to the output of said input buffer and arranged to latch the input address signal;
- a reference circuit connected to another input of said control latch circuit to provide a reference signal;
- and
- two output control circuits connected to two output terminals of said control latch circuit for outputting the address signal.
