;The following is the LS library.
;
;Unless otherwise stated the delays for the following parts are -
;Tplh and Tphl for 15pf and 50 pf respectively.
;
;Unless otherwise stated, delays for flip flops taken from the national
;databook have the following exceptions to the databook -
;The delays for minimum low level clock was extrapolated -
;period - clock high = clock low.
;The min. removal time preset or clear to clock is entered as zero.
;
;
;Unless otherwise specified, delays for the following devices were
;taken from 1984 National Logic Data book.

;The Propagation delays modeled are as follows - Delay from Clock to Q,
;set up and hold time, and the minimum pulse width of the clock.  These
;delays are repeated for 45pf and 150pf.  The Enable/Disable time for
;the 3-state drivers are also modeled for 45pf.
