STMicroelectronics 74ACT374M Octal D-Type Flip-Flop
The 74ACT374M is a high-speed CMOS octal D-type flip-flop integrated circuit designed and manufactured by STMicroelectronics. This device is tailored for high-speed memory buffering applications and features a non-inverting 3-state bus compatible outputs. The 74ACT374M is part of the advanced high-speed CMOS family, which ensures reliable performance with low power consumption.
Each flip-flop has individual clear and clock inputs with the D-type inputs connected directly to the flip-flop. This allows the device to capture the value on the data line when the clock input is in a particular state. The 74ACT374M is designed to have an 8-bit wide format, which means it can handle 8 data inputs and outputs simultaneously, making it ideal for parallel data transfer and storage operations.
The device features a wide operating voltage range from 4.5V to 5.5V, which provides a great deal of flexibility in various application environments. Additionally, the 74ACT374M boasts fast propagation delay times, which is crucial for high-speed operations. Its inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of V<sub>CC.
The outputs of the 74ACT374M are 3-state, which means they can be in a high, low, or high-impedance state. This is particularly beneficial when multiple outputs need to be connected to a common bus, as it allows each output to be effectively disconnected from the bus, preventing bus contention.
With its robust design, the 74ACT374M is characterized for operation from -55°C to 125°C, making it suitable for demanding industrial applications. The device comes in a variety of packages including SOIC, TSSOP, and DIP, providing flexibility for different types of PCB layouts and assembly processes.
In conclusion, the STMicroelectronics 74ACT374M is a versatile and reliable solution for designers looking for a high-performance octal D-type flip-flop. With its fast switching speed, low power consumption, and 3-state outputs, it is well-suited for a wide range of applications including memory buffers, registers, and data storage devices.
