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.

HCT57 circuit using 74hc Text: Even unloaded outputs aren’t consistent, unless you use a pullup resistor.

The pinoutof data are read from the 74HC latches and the address of the destination register is read from. This mainly due datasyeet 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 outputspackage dimensions section on page 3 of this data sheet.

The HC version is output tri-state enabledwhile the data input clock latch is always active. 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.

Look at thresholds and speeds. Home Questions Tags Users Unanswered. But yes they more or less perform the same tasked as a gated 8 bit D latch, except the difference in functions are In logic terms, yes.

This is done by asserting known level. The device inputs are compatible with standard CMOS outputs. NO This mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function. Post as a guest Name.

Does 74HC replaces the 74LS? This latchdatasheeh 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.
