Product Overview: 74LVC377DB by NXP Semiconductors

The 74LVC377DB is a high-performance integrated circuit manufactured by NXP Semiconductors, renowned for its expertise in creating advanced semiconductor solutions. This particular device belongs to the 74LVC family, which is well-known for its low-voltage operation and compatibility with TTL (Transistor-Transistor Logic) levels.

Key Features

  • Octal D-type Flip-Flop: The 74LVC377DB features eight edge-triggered D-type flip-flops, which are ideal for implementing memory and control circuits.
  • Low-Voltage Operation: Designed to operate at a supply voltage ranging from 1.65V to 3.6V, this IC is perfect for battery-operated and low-power applications.
  • 5V Tolerant Inputs: Inputs can tolerate a 5V signal input, which allows for interfacing with 5V logic levels without the need for external components to shift levels.
  • High-Speed Performance: The device supports high-speed signal propagation with a typical propagation delay of only a few nanoseconds, ensuring rapid response in critical applications.
  • Bus-Hold Feature: Integrated bus-hold circuitry on the data inputs eliminates the need for external pull-up or pull-down resistors, simplifying design and reducing component count.
  • Power-Down Protection: All inputs and outputs have power-down protection, providing a safeguard against possible damage during power-off conditions.
  • Latch-Up Performance: The 74LVC377DB exceeds 100 mA in accordance with the JESD78 Class II level B standard, offering robust latch-up performance.
  • ESD Protection: Enhanced Electrostatic Discharge (ESD) protection shields the device from static damage during handling and operation.


The 74LVC377DB is versatile and can be used in a wide range of applications, including:

  • Memory registers
  • Storage devices
  • Control systems
  • Data management systems
  • Embedded systems

With its robust feature set and NXP's commitment to quality, the 74LVC377DB is an excellent choice for designers looking to incorporate reliable flip-flop functionality into their digital logic systems. Its compact DB package allows for efficient use of board space, making it suitable for space-constrained applications.

For detailed specifications, application notes, and more information, designers and engineers are encouraged to consult the official NXP datasheets and product documentation available on the NXP Semiconductors website.
