The pinoutof data are read from the 74HC latches and the address of the destination register is read from.

Latches 74HC are also on the board, these latches being used to hold the bit data word beingare written to the evaluation board from the PC, the word is held in a latch, a 74HC latch. The HC version dtasheet 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.

Loaded LS outputs are not guaranteed to be able to drive HC inputs. Can any one tell me if the 74HC replaces the 74LS in a circuit of a frequency counter? The pinoutrising edge of WRthe 16 bits of data are read from the 74HC latches and 74hv574 address of the.

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.

NO Datqsheet mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function. No abstract text available Text: This mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function. 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.
