Skip to main content. Log In Sign Up. General description The 74HC; 74HCT is a synchronous presettable binary counter with an internal look-head carry.
Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock CP. It causes the data at the data inputs D0 to D3 to be loaded into the counter on the positive-going edge of the clock.
This synchronous reset feature enables the designer to modify the maximum count with only one external NAND gate. The datashdet carry simplifies serial cascading of the counters. This pulse can be used to enable the next cascaded stage. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
