WebThe 74LVC1G125 is a single buffer/line driver with 3-state output. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. WebThe question for today - I have a question concerning the gradient for reflow profiles. Is there any specification or empirical value for the time period the gradient is calculated in, one second, ten seconds, etc..
