74VHCT74AN

Overview

The onsemi 74VHCT74AN is a dual D-type flip-flop featuring independent preset and clear inputs. It operates within a supply voltage range of 2.0 V to 5.5 V, utilizing advanced high-speed CMOS technology. The device provides differential outputs for both Q and /Q states. It supports data transfer to the output during the positive clock transition, with asynchronous control inputs that function independently of the clock signal. The component is housed in a standard DIP-14 package.

Procurement Notes

Verify the specific suffix 'N' against the manufacturer's current product lineup to confirm availability status. Ensure the selected variant matches the required DIP-14 package dimensions and pinout compatibility for your PCB layout. Cross-reference the datasheet revision date to confirm electrical characteristics align with your design specifications.

Selection Notes

Select this component when a dual D-type flip-flop with wide voltage tolerance is required. The VHCT series offers speed comparable to TTL while maintaining low CMOS power consumption. Consider the DIP-14 package if through-hole mounting is necessary for your assembly process or prototyping requirements.

Part Context

This part belongs to the 74VHCT family of advanced high-speed CMOS logic devices. It is functionally compatible with the 74HCT74 standard but offers improved switching speeds. The device is designed for general-purpose digital applications requiring reliable state storage and data transfer capabilities within mixed-signal environments.

Replacement Considerations

The 74VHCT74AM serves as a pin-compatible alternative offering similar functionality. Verify package differences between DIP and SOIC variants before substitution. Other manufacturers producing equivalent VHCT74 parts may require verification of pinout and electrical parameter alignment.
