Device Specification

Semiconductor Group 7-74

AC Testing: Input, Output Waveforms

AC Testing: Float Waveforms

Recommended Oscillator Circuits

AC Inputs during testing are driven at V

- 0.5 V for a logic ’1’ and 0.45 V for a logic ’0’. Timing measure-

ments are made at V

IHmin

for a logic ’1’ and V

ILmax

for a logic ’0’.

For timing purposes a port pin is no longer floating when a 100 mV change from load voltage occurs and

begins to float when a 100 mV change from the loaded V

level occurs. I

≥ ± 20 mA.
