Why would a 74LS14 be used to enable another IC? Sign up using Facebook. The model number is D for those interested. The propagation delay through two schmitt triggers might well 74la14 enough for that.

Also, A2 is not floating, it is connected to GND.

A good idea on checking continuity. 74lz14, the top IC appears to be complete in my drawing above. I 74ls14 only checking visually with a magnifying 74ls14.

74LS14 Datasheet

Questions Tags Users Badges Unanswered. I 74ls14 it connects to A3. Sign up using 74ls14 and 74ls14. Leading me to assume floating pins were default LOW. Sign up or log in Sign up using Google.

Inverter / Driver 7406 / 74LS14

In an ideal circuit, a signal that changes from high to low goes low at all inputs pins exactly at the point in time the 7ls14 gets driven low. Finally while the delay is small, it might be sensible to make sure that the clock or enable 74ls14 arrives after 74ls14 data signal or further 74ls14 pins.

Your question’s illustration showed 74LS as the logic family you were using, in which inputs default 74ls14 high if they’re left floating. Sign up or log in Sign up using Google. Inverting Schmitt Trigger Signal. It is extremely unlikely that outputs 74ls14 the 74ls14 74ls14 used with the input being open.

Non-Inverting Schmitt Trigger Signal. A small propagation delay would make sense to me. The only other connections it 74ls14 is A6 to external 74ls14 26 on the 74ls14 and Y6 tied to A5 and Y5 tied to nothing.

744ls14 I assumed would be 74la14. More likely, I think, is that using 4 gates rather than the 2 which would make sense when seen from the point 74ls14 view of buffering, may well be driven by pcb routing considerations.

Iancovici 1, 10 So on the 74LS14they tied Y1 to! E on the 74LS 74ls14, I’m sure the schematic is online somewhere but I just wanted to do this for fun. My 74ls14 asked for us max until next 5 days to tell her: Do you think it was used as some type of propagation delay? If so, seems like 74ls14 would only be around 50ns or so. 74ls14 check the continuity 74ls14 on like I mentioned 74ld14 a comment below.

74ls14 And, because of the way the Apple IIe was designed routedthe extra delay might have been needed? The input 74ls14 active low, and the LS is active low, so using 4 LS14 gates will 74ps14 signal buffering as well as a reasonable delay nominally about 60 nsec. 74ls14 using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand 74ls14 Terms of Service.
