Metadata#
- Note
- 1 Not more than one output should be shorted at a time. |2 The duration of the short-circuit should not exceed one second.
- Remark
- The output short-circuit current was intended originally to reassure the TTL user that the device would withstand accidental grounding e.g. during in-circuit testing. |This parameter has become a measure of the ability of the circuit to charge the line capacitance and is used to calculate propagation delays. |In CMOS devices there is no need to specify this parameter because the purely capacitive loads allow extrapolation of the ac parameters to calculate the increase in propagation delay.
