ABSTRACT:
A sense amplifier having three transistor stages. A balanced differential input stage with high noise immunity to capacitively coupled noise. A second threshold stage is provided with protection against an output being caused by a permanent potential on the input, false trigger protection circuitry, and protection against supply voltage and other minor variations. A differential output stage increases noise immunity of the amplifier output and protects against a short circuit in the output.
