74HCT393DB

Dual 4-bit binary ripple counter

The 74HC393; 74HCT393 is a dual 4-stage binary ripple counter. Each counter features a clock input (nCP), an overriding asynchronous master reset input (nMR) and 4 buffered parallel outputs (nQ0 to nQ3). The counter advances on the HIGH-to-LOW transition of nCP. A HIGH on nMR clears the counter stages and forces the outputs LOW, independent of the state of nCP. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
