74LVC377D,118

Overview

The 74LVC377D,118 is an octal D-type flip-flop manufactured by Nexperia USA Inc., belonging to the 74LVC logic series. It features positive-edge triggering and non-inverting outputs within a single circuit configuration. The device operates on a supply voltage range of 1.2 V to 3.6 V and supports surface-mount installation in a 20-SOIC package measuring 0.295 inches (7.50 mm) wide. It exhibits a maximum propagation delay of 8.2 ns at 3.3 V with 50 pF load, alongside high output drive capabilities of 24 mA for both high and low states. The component maintains a static current of 10 µA and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Octal D-type flip-flop architecture providing eight independent data storage elements within a single integrated circuit package.
• Positive-edge triggered operation ensures precise data capture synchronized with clock signal transitions.
• High-output drive capability of 24 mA supports direct interfacing with loads without additional buffering.
• Extended operating temperature range enables reliable performance in demanding industrial and commercial environments.

Applications

• Parallel-to-serial data conversion circuits requiring stable latching of multi-bit information.
• Register stages in digital signal processing systems for temporary data storage and synchronization.
• Memory interface buffers managing data flow between microprocessors and peripheral devices.
• State machine implementations utilizing multiple flip-flops for complex sequential logic control.

Procurement Notes

Verify the specific suffix '118' corresponds to the standard tape-and-reel packaging format intended for automated assembly processes. Confirm that the 20-SOIC footprint matches the designated PCB land pattern dimensions precisely. Ensure compatibility with the target supply voltage limits not exceeding 3.6 V to prevent device damage. Check for any recent Product Change Notifications regarding marking or material composition updates before finalizing procurement orders.

Selection Notes

Select this component when an octal register with positive-edge triggering is required for high-speed digital applications. The 74LVC series offers superior speed compared to standard LVC variants while maintaining low power consumption suitable for battery-operated devices. Consider the 20-SOIC package for designs prioritizing thermal dissipation and mechanical stability over space-constrained alternatives like TSSOP. Validate input voltage levels against the 1.2 V to 3.6 V operational range to ensure proper logic threshold compliance.

Part Context

This part belongs to the broader 74LVC family of low-voltage CMOS logic devices, designed for interoperability with various digital systems. The 74LVC377 specifically addresses the need for parallel data storage in compact form factors. Its designation distinguishes it from latch-based counterparts like the 74LVC373 by employing edge-triggered behavior rather than level-sensitive transparency. This classification places it firmly within sequential logic components used for timing and state management.

Replacement Considerations

Publicly confirmed substitute part numbers include 74LVC377PW,118, which utilizes a 20-TSSOP package instead of SOIC. Designers must verify pinout compatibility and physical dimension differences when swapping between these package types. Other family members such as 74LVC273D,118 offer similar functionality but may differ in specific electrical characteristics or package availability.
