Product Overview: 74LVC273DB from NXP Semiconductors

The 74LVC273DB is a high-performance, low-voltage octal D-type flip-flop with a clear feature, manufactured by NXP Semiconductors. This integrated circuit is part of the LVC family, which stands for Low-Voltage CMOS, indicating that it operates with a lower power supply voltage ranging from 1.2V to 3.6V. This makes it particularly suitable for battery-operated devices and for interfacing with 3.3V systems.

The device is characterized by its high-speed performance while maintaining a low power consumption. This is achieved through the use of advanced silicon-gate CMOS fabrication. The 74LVC273DB is designed to have a broad VCC operating range and provides the feature of 5V tolerant inputs/outputs for interfacing with 5V logic levels without the risk of damage.

Each flip-flop has a direct clear input and is edge-triggered, which means that data is entered on the rising edge of the clock signal (CLK). The flip-flops are ideal for storing data and can be cleared simultaneously by asserting the clear input (CLR) low. This feature makes the device extremely useful in a variety of applications where data synchronization or temporary data storage is required, such as in registers, counters, and control circuits.

The 74LVC273DB comes in a DB package, which is a small-outline integrated circuit (SOIC) with a body width of 7.5mm. It has a pin count of 20 pins, which includes the data inputs (D0-D7), clock input (CLK), clear input (CLR), outputs (Q0-Q7), VCC, and ground (GND). The package is designed for surface mount technology (SMT), which allows for efficient assembly and space-saving PCB design.

In summary, the 74LVC273DB is a versatile octal D-type flip-flop that offers high-speed operation with the convenience of low-voltage power supply requirements. Its 5V tolerant I/Os and wide operating voltage range make it compatible with a variety of logic levels, ensuring seamless integration into mixed-voltage systems. This device is an excellent choice for designers looking for a reliable flip-flop that can perform in demanding environments while minimizing power consumption.
