Part Number: SN74LV123A Hi All,
Customer is using the SN74LV123A to drive the LED of an optocoupler with 100 ohm resistor in series.
The SPICE simulation shows that the output drops (1Q) to ~1.5V with 2.7 mA being drawn, Vdd is 3.3V and ~ 1.4V…
Part Number: SN74LV123A Other Parts Discussed in Thread: SN74LVC1G123 Hello,
My customer uses only channel 2 of SN74LV123A.
Can they leave pin#15 (1Rext/Cext) unconnected?
Best regards,

Part Number: SN74LV123A I am using the part SN74LV123ADR in my design. I want to know the maximum supply current drawn by the device at VCC = 5V. Value is required to prepare power analysis.
Part Number: SN74LV123A Please let me know about unused channel for SN74LVC123A below;
①Are input side (/A, B, /CLR) connect to GND, is is correct?
②Is Rext pin left open, no problem?
Because Datasheet P12 - figure 7 is described when CLR: Low…
Part Number: SN74LV123A Hi, Team:
My customer meet a SN74LV123 application, base on the datasheet description,
when /CLR = HIGH, /A = Low, B = Rising edge, there are pulse at the /Q output. But from the below waveform, there are pulse no matter the…
Part Number: SN74LV123A Other Parts Discussed in Thread: SN74LVC1G123 Hello E2E Logic Forum Members,
Our customer asked the typical value of Rext/Cext Input current(II) and the reference voltage of the comparator between Rext and Output.
As for…
Part Number: SN74LV123A Hi team,
Do you have the user guide for how to choose the value of the K, RT and CT when I fix the Tw value?
So for the same Tw, should I use larger cap or larger resistor?
Do you recommend to set the K to be 1?

Part Number: SN74LV123A Hi all,
I have a question about Cext pin of SN74LV123A.
According to SCLS393O version, Cext is connected to GND, but from new versions after SCLS393P, Cext is not connected to GND.
Is there any change on this design?
Which…
