Line 5: == How to use this module == This module is designed to connected to either a 16 or 8 bit bus, and contains two latches that can be latches independently. For a backplane/bus common ~~Veroboard or strip board~~[[stripboard]] may be used, along with 0.1 pitch 90° headers. It can be used with the [[~~Ken Stone~~CGS parallel port adapter for IBM PCs\|parallel port adapter for IBM PCs]] parallel port adapter], which is how Ken used his. Software is up to the individual. While untested, the analog portion of the module should work on 12 volts. The digital portion requires 5 volts.

The obsolete 74LS273 can be used if '''A''' is linked to '''B''' instead of '''D'''. Check your data books. * 10 to 22 ohm resistors can be used instead of the ferrite beads. If you don't care about power-rail noise, just use a link instead. == CC-BY-NC == Readers are permitted to construct these circuits for their own personal use only.
