Frequently Asked Questions

What is the supply voltage range for the SN74AHC74D?

The SN74AHC74D operates over a supply voltage range of 2V to 5.5V, making it compatible with both 3.3V and 5V logic systems. This wide range provides flexibility for integration into various microcontroller and FPGA-based designs.

What package type does the SN74AHC74D come in?

The SN74AHC74D is available in a SOIC-14 (Small Outline Integrated Circuit, 14-pin) surface-mount package. This compact package is suitable for high-density PCB designs and is compatible with standard pick-and-place assembly processes.

What are the typical applications of the SN74AHC74D?

The SN74AHC74D is commonly used in digital systems for data latching, frequency division by two, and state machine design. Typical applications include microcontroller bus interfaces, clock synchronization circuits, shift register stages, and sequential logic control in industrial and consumer electronics.

How does the asynchronous set and reset work on the SN74AHC74D?

The SN74AHC74D features active-low asynchronous set (PRE) and reset (CLR) inputs that override the clock and data inputs. When PRE is asserted low, the Q output is forced high; when CLR is asserted low, Q is forced low. These inputs allow immediate state initialization independent of the clock signal.
