AC Electrical Characteristics
- ST-BUS Output Tristate Timing
Characteristics are over recommended operating conditions unless otherwise stated.
Typical figures are at 25
°
C and are for design aid only: not guaranteed and not subject to production testing.
* Note 1: High Impedance is measured by pulling to the appropriate rail with R
L
, with timing corrected to cancel the time taken to discharge C
