SN74HC273DBR Octal D-Type Flip-Flops with Clear

The SN74HC273DBR is a high-performance integrated circuit from Texas Instruments, designed to provide reliable and efficient data storage functionality. This particular model is part of the HC family, which signifies the use of high-speed CMOS technology to achieve the perfect balance between speed and power consumption.

At the heart of the SN74HC273DBR are eight edge-triggered, D-type flip-flops with a direct clear input. These flip-flops are capable of storing eight individual bits of data, making the device ideal for applications where temporary storage of data is required, such as in registers, counters, and control circuits.

Key Features:

• Logic Type: Octal D-Type Flip-Flops with Clear
• Package / Case: SSOP-20
• Mounting Type: Surface Mount
• Operating Temperature: -40°C to 85°C, making it suitable for a wide range of environmental conditions.
• Supply Voltage: 2 V to 6 V, allowing for use in various power environments and compatibility with TTL levels.
• Output Current: High-level output current of -6 mA and low-level output current of 6 mA, providing strong signal driving capabilities.

The device features a common clear input (CLR) that, when taken low, will reset all flip-flops, ensuring that the output is low regardless of the data inputs. This feature is crucial for initializing systems and maintaining data integrity during power-up sequences or after error conditions.

Additionally, the SN74HC273DBR is designed for a wide operating voltage range and has a low power consumption, making it an excellent choice for battery-powered or energy-sensitive applications. The inputs are also characterized for operation from 5V down to VCC to ensure compatibility with a variety of logic levels.

Its robust design includes latch-up performance that exceeds 250 mA per JESD 17, and it is ESD protection tested for greater reliability in sensitive applications. The SN74HC273DBR is supplied in a slim SSOP-20 package, which is ideal for space-constrained applications while still offering the benefits of surface-mount technology.

With its combination of features, the SN74HC273DBR from Texas Instruments is a versatile and reliable choice for designers looking to implement efficient data storage and signal synchronization in their digital systems.
