7400 competition entry: Illogical Dickson Doubler

Posted on Thursday, October 20th, 2011 in 7400 contest by DP

Jonathan entered his illogical Dickson doubler into the Open 7400 Logic Competition.

My entry demonstrates how you can use the internal protection diodes and back powering to power a 74HC14 at a voltage “double” (minus diode drops) that of the primary power supply. This method was tested on a 74HC14 and a 74HC595, but it should work on any IC that uses clamping diodes for I/O protection.

Via the contact form.

    Very cool misuse! I wish misuse had it’s own category.
