SN74LVC1G79DCKR

Flip Flops Overview

The SN74LVC1G79DCKR is a single positive-edge-triggered D-type flip-flop from Texas Instruments, designed for operation within a 1.65V to 5.5V supply voltage range. It features a SC-70-5 NanoFree package and supports CMOS/TTL inputs. The device offers a maximum propagation delay of 5ns at 5V with a 50pF load and provides output drive currents of ±32mA. It includes Ioff support for partial power-down applications and meets JESD78 Class II latch-up standards.

Flip Flops Feature Summary

• Positive-edge-triggered D-type flip-flop functionality
• Ioff circuitry prevents back-driving during partial power-down
• Supports 5.5V tolerant inputs for level translation
• NanoFree SC-70-5 packaging for space-constrained designs

Flip Flops Applications

• Test and measurement equipment
• Telecommunications infrastructure
• Consumer electronics

Flip Flops Procurement Notes

Verify the specific ordering suffix 'RG4' against the manufacturer's current catalog to confirm RoHS compliance status and exact revision level. Ensure the SC-70-5 package variant matches the required PCB footprint dimensions. Cross-reference the datasheet version date to validate operating temperature ranges and electrical characteristics before finalizing component selection.

Flip Flops Selection Notes

Select this component when a compact, single-bit storage element is required for low-voltage digital logic systems. The LVC series ensures compatibility with modern microcontrollers while maintaining robust noise immunity. Consider the 5ns propagation delay for timing-critical paths and verify that the 32mA output current suffices for the intended load capacitance and fan-out requirements in the target application design.

Flip Flops Part Context

This part belongs to the SN74LVC1Gxx family of ultra-small single-gate logic devices. It shares the same NanoFree SC-70-5 footprint as other members like the SN74LVC1G07 and SN74LVC1G126, facilitating modular design strategies. The LVC technology allows direct interfacing between 1.65V and 5.5V domains without external level shifters, simplifying system architecture.

Flip Flops FAQ

Does the SN74LVC1G79DCKR support partial power-down mode?

Yes, it includes an Ioff circuit that disables outputs when VCC is below 1.5V, preventing back-driving current into the device.

What is the input voltage tolerance of this flip-flop?

The inputs are 5.5V tolerant, allowing them to accept signals up to 5.5V even if the device is powered by a lower voltage such as 3.3V or 1.8V.
