MOS Buffer for receiving TTL level signals |
摘要 |
An MOS buffer is described which converts TTL level signals to MOS level signals. An inverter which receives the input TTL signal is coupled to ground through a reference voltage source. This source assures that the inverter does not conduct when the TTL level signal is in its lower state. The output of the inverter is coupled to a level shifter which assures that the output of the inverter is shifted downward when the TTL signal is in its higher state. The transistors in the buffer may have short channels unlike prior art circuits.
