Part Number: SN74LV273A hi,
The Q output is occasionally not kept low even after CLR is already set at low during power-up in which the CLK and CLR ramp up speed is very low (rise speed is 3.3v/2s). The detail test waveforms are attached.
Part Number: SN74LV273A Dear expert.
My customer will face the shortage because of these tight situation, but we want to use your products.
So could you inform me what is alternative of SN74LV273APWR ?
If possible, could you check it with something in stock…
Part Number: SN74LV273A Dear sir:
May I have some confirming item for SN74LV273A application ?
If original our circuit use 74LVC273PW ,TI SN74LV273A part could replace it ? Or Any need consider or Risk ?
Part Number: SN74LV273A Hi,I have used SN74LV273 in my design,i have two questions
1.what is the inital state of Q output,in my design is high level output,even i put clear pin low for about 20ms after power on
2.in the datasheet table 2 of truth table…
Other Parts Discussed in Thread: SN74LV273A What is the SN74LV273A latch point ?
In datasheet, the Vih is Vcc*0.7; Does it means the Clk vih or Vin(data input)?
The VOLTAGE WAVEFORMS SETUP AND HOLD TIMES In datasheet, it also shows the 50% Vcc.
I am confused…
I can confirm that is the case. I'll put in our queue to get fixed. Thanks for bringing it to our attention. Are you wanting BJT circuitry? This device is older and a newer device like the SN74LV273A should give you better performance.…
