Hey Deshawn, The Timing Requirements can be found can be found on page 5 of the datasheet. However, when you boot the device, the output will be unknown so it's very possible that sometimes you have Q output high and sometimes Low during your bootup.…
Part Number: TCA9539-Q1 Other Parts Discussed in Thread: SN74LVC1G80-Q1 , , SN74HCS74-Q1 Dear team,
According to below description, INT pin will be low when input signal has rising or falling edge. My customer hopes that INT pin only be triggered by rising…
Part Number: SN74LVC7Hello,
Could I use an RC circuit on the /CLR pin?
I saw that in the datasheet that the input transition rise and fall time should be in 10ns/V. But I dont understand what it will be the issue on this asynchronous pin.
Moreover, this…
The rising edge is much too slow, and might damage the device. See [FAQ] How does a slow or floating input affect a CMOS device?
Add a Schmitt-trigger buffer, or use the SN74HCS74 instead.
Part Number: SN74LVC1G80 Other Parts Discussed in Thread: SN74LVC1G79 , , SN74HCS74 My customer want to default output low level，but when use SN74LVC1G80,it default output low level.Can I use SN74LVC1G79 to output low level by default?
Blow is the customer's…
Part Number: SN74LVC1G79 Other Parts Discussed in Thread: SN74HCS74 Does this part (likewise, the "LVC1G80, 'LVC2G79 and 'LVC2G80) have any type of internal power-on reset that guarantees the start-up state of the Q (or /Q) output? Or do they just…
Hey Peter,
Can you show scope shots?
Also I'd check out the SN74HCS74 device. In the applications section, you will see a similar application. It may work better for you.
Hi Yamaguchi,
The inputs and outputs of the SN74HC74 have an input and output protection structure that is similar to the one shown in figure 11 of the SN74HCS74 datasheet.
This means that, so long as the input & output clamp diode current ratings (+…
