Applications
The SN74LVC1G74DCUR is widely used in digital clock dividers, state machines, and edge-detection circuits where a single flip-flop with independent clear and preset is required. It is suitable for portable electronics, IoT nodes, and battery-powered devices that benefit from its 1.65 V to 5.5 V supply range and low quiescent current. The SOT-23 footprint makes it a preferred choice for space-constrained designs in wearables, industrial sensors, and communication modules.

Frequently Asked Questions
What is the maximum operating frequency of the SN74LVC1G74DCUR?
The SN74LVC1G74DCUR supports a maximum clock frequency of 175 MHz at nominal supply voltage. This makes it suitable for high-speed digital logic applications including clock dividers, synchronizers, and fast state-machine designs operating in the LVC voltage range of 1.65 V to 5.5 V.
What supply voltage range does the SN74LVC1G74DCUR support?
The device operates across a wide supply voltage range of 1.65 V to 5.5 V, making it compatible with both 1.8 V and 3.3 V logic systems as well as legacy 5 V designs. This flexibility simplifies level-matching in mixed-voltage systems and portable, battery-operated applications.
What package does the SN74LVC1G74DCUR come in, and what does the 'DCUR' suffix mean?
The 'DCUR' suffix denotes a SOT-23 (SC-70 style) 8-pin small-outline package. This ultra-compact surface-mount package has a very small PCB footprint, making it ideal for space-constrained designs such as wearables, IoT modules, and handheld devices where board real-estate is at a premium.
Can the SN74LVC1G74DCUR be used as a frequency divider?
Yes. By connecting the Q-bar output back to the D input, the SN74LVC1G74DCUR can be configured as a divide-by-2 frequency divider. Combined with its 175 MHz maximum frequency and low propagation delay, this configuration is commonly used to generate clock sub-harmonics in digital and RF systems.
What are common alternatives or replacements for the SN74LVC1G74DCUR?
Pin-compatible or functionally equivalent alternatives include the NXP 74LVC1G74, Nexperia 74LVC1G74, and ON Semiconductor MC74LVC1G74. All share the same single D flip-flop topology with clear and preset inputs in a similar SOT-23 package. Always verify timing parameters and package pinout before substitution.
