Hello,
While referencing the datasheet for the SN74LV123A-Q1 monostable multivibrator, we noticed some discrepancies and we need some clarification. The pin function table (page 3) shows 1B should be LOW when trigger input for falling edge is 1A; 1A should be HIGH when trigger input for rising edge is 1B; 1A should be HIGH and 1B should be LOW when trigger input for rising edge is 1CLR. However, the truth table (page 12) shows 1B should be HIGH when trigger input for falling edge is 1A; 1A should be LOW when trigger input for rising edge is 1B; 1A should be LOW and 1B should be HIGH when trigger input for rising edge is 1CLR.
What are the correct inputs for 1A, 1B and 1CLR? Is the Pin Function table correct? Or is the truth table correct?
Page 3 shows the following pin functions:
Page 11 truth table shows the following inputs:
