Derating Curves over Extended Operating Frequencies (HEDS-9000/9100/9200
Extended Series)
Below are the derating curves for state, duty, phase and V
240 kHz (recommended maximum frequency is 100 kHz). The curves were derived using standard TTL load.
–40 C operation is not feasible above 160 kHz because V
state high) beyond that frequency.
