1. Consult factory for availability of higher frequencies.
2. HCMOS Load - See Load circuit diagram #2. Consult factory with nonstandard output load requirements.
3. Rise/Fall times are measured between 0.5 V and 2.4 V with TTL load, and between 10% Vdd and 90% Vdd with
HCMOS load.
NOTE: A capacitor of value 0.01
F or greater between Vdd and
Ground is recommended.
