HEF4520B
Dual binary counter
12. Waveforms
a. nCP0 and nCP1 set-up times, propagation delays and output transition times
b. nMR recovery time, minimum nCP0, nCP1, and nMR pulse widths and maximum frequency
Measurement points are given in
Table 9
.
The logic levels V
OH
and V
OL
are typical output voltage levels that occur with the output load.
