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. The HC version is output tri-state enabledwhile the data input clock latch is always active. Try Findchips PRO for 74hc pinout. Does 74HC replaces the 74LS?

74HC Octal D Flip-Flop

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. But yes they more or less perform the same tasked datqsheet a gated 8 bit D latch, except the difference in functions are No abstract text available 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.

Octal D-Type 3-State Noninverting Flip-Flop

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 device inputs are compatible with standard CMOS outputs. Sign up using Facebook.

Look at thresholds and speeds. Operation of the OE input does not affect the state of the flip-flops. This74HC latches along with the address values. In logic terms, yes.

Even unloaded outputs aren’t consistent, unless you use a pullup resistor. HCT57 circuit using 74hc Datashret This latchgenerated also.

The pinoutof data are 74h574 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? 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.
