74HC574 DATASHEET PDF

The 74HC is identical in pinout to the LS The device inputs dimensions section on page 3 of this data sheet. ORDERING INFORMATION. 74hc Flip Flops are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for 74hc Flip Flops. The MM74HC high speed octal D-type flip-flops utilize advanced silicon-gate P-well CMOS technology. They pos- sess the high noise immunity and low.

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

The device inputs are compatible with standard CMOS outputs. No abstract text available Text: Home Questions Tags Users Unanswered.

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 datasheef, a 74HC latch. This mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function.

This is done by asserting known level. The HC version is output tri-state enabledwhile the data input clock latch is always active. Email Required, but never shown.

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. Post as a guest Name. Previous 1 2 ddatasheet Can any one tell me if the 74HC replaces the 74LS in a circuit of a frequency counter?

But yes they more or less perform the same tasked as a gated 8 bit D latch, except the difference in functions are Operation of the OE input does not affect the state of the flip-flops.

74HC Octal D Flip-Flop

Even unloaded outputs aren’t consistent, unless you use a pullup resistor. Loaded LS outputs are not guaranteed to be able to drive HC inputs. NO This mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function. In logic terms, yes. The device inputs are compatible with standard CMOS outputspackage dimensions section on page 3 of this data sheet.
