TEXT 48 648 Left 0 ;NODE ASSIGNMENTS:\nThe first node up through to the fifth are reserved for inputs.  For differential inputs the first node is used \nas the noninverting one and the second as the inverting half of the pair.  The seventh node is the main \noutput with the sixth node serving as a complementary inverting output if needed.  Node 8 serves as the \ngate's common.  Unconnected nodes are connected by the netlister to the gate's common (that unlabeled \npin in the corner).  This is a flag to the compiler to remove them and is different than tying the node to \ncommon with a wire.
TEXT 48 848 Left 0 ;GENERAL GATE PARAMETERS (defaults shown):\nVhigh=1 Vlow=0 (logic levels); Ref=50% (logic threshold - if set becomes an absolute voltage); \nTd=0 (delay time: should be set to 10ns for shift registers and counters and the like);\nTrise=0 Tfall=Trise OR Tau=0 (transistion time constant) OR Rout=0 and Cout=0;\ntripdt=not specified (sets the maximum step size during logic transistions while between 10% and 90%)
TEXT 48 992 Left 0 ;SCHMITT PARAMETERS:\nVt (threshold) Vh (hysteresis: band = 2*Vh)  Note: if not specified Vt defaults to 50% and Vh to 5%
TEXT 48 1120 Left 0 ;VARISTOR PARAMETERS:\nRclamp=0 (clamping impedance)
TEXT 48 1056 Left 0 ;MODULATOR PARAMETERS:\nmark=? space=? (either specify mark and space frequencies or use a look-up table, not both)
