No abstract text available Text: But yes they more or less perform the same tasked as a gated 8 bit D latch, except the difference in functions are Sign up using Email and Password. HCT57 circuit using 74hc Text: NO This mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function. This latchgenerated also. Can any one tell me if the 74HC replaces the 74LS in a circuit of a frequency counter?

This is done by asserting known level. The device inputs are compatible with standard CMOS outputs. Post as a guest Name.

datashret In logic terms, yes. The HC version is output tri-state enabledwhile the data input clock latch is always active. The device inputs are compatible with standard CMOS outputspackage dimensions section on page 3 of this data sheet.

Latches 74HC are also on the board, these latches being used to hold the bit data wordto the evaluation board from the PC, the word is held in a latch, a 74HC latch. Operation of the OE input does not affect the state of the flip-flops.

Does 74HC replaces the 74LS? Even unloaded outputs aren’t consistent, unless you use a pullup resistor.

This74HC latches along with the address values. Email Required, but never shown. The pinoutof data are read from the 74HC latches and the address of the destination register is read from.

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.
