The LS version is enables changes on input data to be clocked while the output is always active The HC version is output tri-state enabledwhile the data input clock latch is always active. Very Good Average Fair Poor. Track my order s.

It will remain in our system until you withdraw your consent. Operation of the OE input does not affect the state of the flip-flops. In logic terms, yes.
The 74HC is an octal D-type flip-flops featuring separate D-type inputs for each flip-flop and 3-state outputs for bus-oriented applications. Available for 74uc574 order. Home Questions Tags Users Unanswered.
flipflop – 74HC or 74LS? – Electrical Engineering Stack Exchange
We GRobotronics also save your IP address as a security precaution, but in can only be viewed by our staff. Loaded LS outputs are not 74hc5744 to be able to drive HC inputs. Does 74HC replaces the 74LS? Sign in Register Email.
THe reason the part numbers changed root number xxx is due to the functional differences in output enable to tri-state for the HC version. A clock CP and an output enable OE input are common to all flip-flops. Register for a new account. Password Forgot your password?

I looked at their data sheet and found out they are similar regardless their pin out, may be i’m missing some the big picture ao that’s why i’m asking precisely if they do function the same, thanks for any info that helps. Post as a guest Name. NO This mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function. Orders Wish list Track my order s.
