Look at thresholds and speeds. Latches 74HC are also on the board, these latches 74h574 used to hold the bit data word dstasheet, to the evaluation board from the PC, the word is held in a latch, a 74HC latch.

Does 74HC replaces the 74LS? This is done by asserting known level. 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. NO This mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function.

Operation of the OE input does not affect the state of the flip-flops. This mainly datzsheet to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function. Email Required, but never shown. Try Findchips PRO for 74hc pinout.

In logic terms, yes. But yes they more or less perform the same tasked as a gated 8 bit D latch, except the difference in functions are If this implies can it be blindly substituted for an existing design using 74LS part?

Can any one tell me if the 74HC replaces the 74LS in a circuit of a frequency counter? The pinoutof data are read from the 74HC latches and the address of the destination register is read from. No abstract text available Text: The device inputs are compatible with standard CMOS outputspackage dimensions section on page 3 of this data sheet.

Even unloaded outputs aren’t consistent, unless you use a pullup resistor. The pinoutrising edge of WRthe 16 bits of data are read from the 74HC latches and the datsaheet of the.

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.
