AN-1015 GreenPAK Macro Circuit Design: Active HIGH Latch

Digital Latches are functions with deep feedback for holding its state after switching by input signal from one state to another until Reset signal comes. This simple unit has one input and output, main part of which is 4-bit LUT0 (look-up table) with feedback to “memorize” input signal and hold it, see Figure 1.
