Product Overview: SN74HCT74NSR from Texas Instruments

The SN74HCT74NSR is a high-performance, dual D-type positive-edge-triggered flip-flop integrated circuit brought to you by Texas Instruments, a leader in semiconductor design and manufacturing. This device is part of the '74HCT' family, which is compatible with standard CMOS integrated circuits but has the added benefit of TTL input compatibility.

The SN74HCT74NSR offers features that make it ideal for a wide array of applications, including buffer storage, shift registers, data storage, and pattern generators, to name a few. The device contains two independent D-type flip-flops with direct clear and preset inputs. Information on the input is transferred to the outputs on the positive-going edge of the clock pulse. Clear and preset are independent of the clock and are initiated by a low-level signal at either input.

This product comes in an SOP (Small Outline Package) with a 'NS' designator and is supplied in tape and reel form (indicated by the 'R'), making it suitable for automated assembly processes. The SN74HCT74NSR operates at a voltage range of 4.5V to 5.5V, which is typical for 5V digital logic, providing a good margin for stability and noise immunity.

Key Features:

• Wide Operating Voltage Range of 4.5V to 5.5V
• Outputs Can Drive Up To 10 LSTTL Loads
• Low Power Consumption, 20-µA Max ICC
• Typical tpd = 13 ns
• ±4-mA Output Drive at 5 V
• Low Input Current of 1 µA Max
• Direct Clear and Preset Inputs

The device's performance is characterized for operation from -40°C to 85°C, ensuring reliability across a wide temperature range, making it suitable for industrial applications. Its low power consumption and high noise immunity are hallmarks of the 'HCT' logic family, guaranteeing efficient operation in electronic circuits.

In summary, the SN74HCT74NSR from Texas Instruments is a robust, versatile flip-flop IC that integrates well with both CMOS and TTL logic families, offering designers flexibility and high performance in their digital logic applications.
