Tony EE rocketscientist 62k 2 21 Loaded LS outputs are not guaranteed to be able to drive HC inputs.

The pinoutrising edge of WRthe 16 bits of data are read from the 74HC latches and the address of the. NO This mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx eatasheet and differences in the Disable function.

In logic terms, yes. Previous 1 2 This mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function.

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.

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.

Operation of the OE input does not 74c574 the state of the flip-flops. 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. The pinoutof data are read from the 74HC latches and the address of the destination register is read from.

If this implies can it be blindly substituted for an existing design using 74LS part?
