The 74HC is identical in pinout to the LS The device inputs dimensions section on page 3 of this data sheet. ORDERING INFORMATION. 74hc Flip Flops are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for 74hc Flip Flops. The MM74HC high speed octal D-type flip-flops utilize advanced silicon-gate P-well CMOS technology. They pos- sess the high noise immunity and low.

This74HC latches along 74hc57 the address values. This mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function. The device inputs are compatible with standard CMOS outputs. Latches 74HC are also on the board, these latches dayasheet used to hold the bit data wordto the evaluation board from the PC, the word is held in a latch, a 74HC latch.

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. The pinoutrising edge of WRthe 16 bits of data are read from the 74HC latches and the address of the.

This latchgenerated also. 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.

But yes they more or less perform the same tasked as a gated 8 bit D latch, except the difference in functions are HCT57 circuit using 74hc Text: Even unloaded outputs aren’t consistent, unless you use a pullup resistor.

Look at thresholds and speeds. 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.

This is done by asserting known level. Home Questions Tags Users Unanswered. Can any 74yc574 tell me if the 74HC replaces the 74LS in a circuit of a frequency counter?

Operation of the OE input does not affect the state of the flip-flops. If this implies can it be blindly substituted for an existing design using 74LS part? Previous 1 2 Post as a guest Name. Sign up using Email and Password. In logic terms, yes.
