Data for temperatures below 0°C and above 70°C are applicable to the SN55ALS194 circuits only.
NOTES: A. The A input is connected to V
CC
during the testing of the Y outputs and to GND during the testing of the Z outputs.
B. The A input is connected to ground during the testing of the Y outputs and to V
CC
during the testing of the Z outputs.
