ON Semiconductor DM74LS279N - Quad S-R Latch

The DM74LS279N is a high-performance quad S-R (Set-Reset) latch integrated circuit produced by ON Semiconductor, a leading name in the semiconductor industry. This device is designed to provide optimal performance in digital systems where the need for stable and reliable latching functions is essential. The DM74LS279N is part of the 74LS family, which is known for its low-power Schottky technology, offering a perfect balance between speed and power consumption.

Each latch in the DM74LS279N device operates independently, with two inputs: a set (S) input and a reset (R) input. The outputs provide both the normal and complementary states. The latches are designed to be triggered by a high level on the set input or reset input. When the set input is high while the reset input is low, the output goes high and remains high even after the set input returns to low, until the reset input is triggered. Conversely, when the reset input is high and the set input is low, the output is reset to low. If both set and reset inputs are low, the output retains its previous state.

The DM74LS279N is packaged in a standard 14-pin DIP (Dual In-line Package), making it easy to integrate into various circuit boards. It is characterized for operation over the full military temperature range of -55°C to +125°C, ensuring reliability in a wide range of environments and applications. This device is commonly used in control systems, computer systems, and other applications where data needs to be stored temporarily and stability is critical.

Key features of the DM74LS279N include:

• Quad set-reset latches for increased versatility
• Low power consumption with Schottky technology
• Independent operation of each latch
• Direct clear input
• Guaranteed output drive capability
• Compatibility with other 74LS series logic devices

Overall, the ON Semiconductor DM74LS279N represents a reliable and efficient solution for digital systems requiring stable latching mechanisms. Its robust design and compatibility with other logic families make it a valuable component for designers and engineers working on a wide array of electronic projects.
