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.

This is done by asserting known level.
But yes they more or less perform the same tasked as a gated 8 bit D latch, except the difference in functions are In logic terms, yes. THe reason the part numbers changed root number xxx is due to the functional differences in output enable to tri-state for the HC dtaasheet.

Post as a daatasheet Name. NO This mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function. The HC version is output tri-state enabledwhile the data input clock latch is always active.

No abstract text available Text: The device inputs are compatible with standard CMOS outputspackage dimensions section on page 3 of this data sheet. Try Findchips PRO for 74hc pinout. If this implies can it be blindly substituted for an existing design using 74LS part?

The pinoutof data are read from the 74HC latches and the address of the destination register is read from. This latchgenerated also. Even unloaded outputs aren’t consistent, unless you use a pullup resistor.
Tony EE rocketscientist 62k 2 21 Look at thresholds and speeds. 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 daasheet is held in a latch, a 74HC latch.
