The 74AUP1G386GF is a mini logic gate that provides a single 3-input EXCLUSIVE-OR function. Its input can be driven across the entire V CC range from 0.8 V to 3.6 V. The circuit is tolerant to slower ...

[IMSAI Guy] grabbed an obsolete XOR gate and tried a classic circuit to turn it into a frequency doubler. Of course, being an old part, it won’t work at very high frequencies, but the circuit is super ...
