The HCC4044BF from STMicroelectronics is a high-quality integrated circuit that features quadruple R-S (reset-set) latches with 3-state outputs. This component is part of the HCC40xxx series, a family of monolithic integrated circuits fabricated in Metal Oxide Semiconductor technology available in both standard dual-in-line and surface mount packages.
Each latch in the HCC4044BF has an independent R-S function with a common enable input. The enable input is active at the high logic level, allowing the latches to store the information present on the S and R inputs. When the enable input is taken low, the information that was present at the last moment before the transition is retained or latched. Furthermore, the 3-state outputs provide a high-impedance state, allowing for the use in bus-oriented applications.
The HCC4044BF operates over a broad voltage range, from 3V to 20V, providing versatility in various applications and compatibility with TTL, CMOS, and other logic families. This feature makes the HCC4044BF ideal for interfacing with different types of digital systems and for use in applications requiring a wide power supply range.
The device is characterized for operation from -55°C to 125°C, ensuring reliable performance in extreme environmental conditions. This temperature range makes the HCC4044BF suitable for automotive, industrial, and military applications where robustness and reliability are critical.
In summary, the HCC4044BF from STMicroelectronics is a versatile and reliable component that is well-suited for a variety of digital applications. Its 3-state outputs, wide voltage range, and high-temperature operation make it an excellent choice for designers looking for a quadruple R-S latch solution.
