Product Overview: MC74AC374DWR2G by ON Semiconductor

The MC74AC374DWR2G is a high-performance, octal D-type flip-flop with 3-state outputs from ON Semiconductor. This integrated circuit is designed to provide essential functions for digital systems, where it captures the values on the D-inputs at the rising edge of the clock (CK) input. Once captured, the data is held in the flip-flop until the next rising edge of the CK input.

The MC74AC374DWR2G features eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The common clock (CK) and master reset (MR) inputs allow synchronized operation of all flip-flops. The master reset input is active LOW and can be used to reset the device at any time, independent of the clock signal, ensuring that the Q outputs are in a known state when needed.

The outputs of the flip-flops are 3-state, which means they can be in a high, low, or high-impedance state. The 3-state outputs allow for connection to a bus-oriented system without the need for external bus drivers. This is controlled by the Output Enable (OE) input, which is active LOW. When OE is LOW, the normal operation of the flip-flops is enabled, and when OE is HIGH, the outputs are in a high-impedance state. This feature is particularly useful for address latching in microprocessor systems.

The MC74AC374DWR2G is housed in a 20-pin SOIC package, which provides a compact footprint for space-constrained applications. It operates over a wide voltage range of 2V to 6V and features a typical operating temperature range from -40°C to +85°C, ensuring reliable performance across various environmental conditions.

ON Semiconductor has designed the MC74AC374DWR2G with advanced CMOS technology to achieve high speed and low power consumption. It is a versatile component suitable for a wide range of applications, including memory address registers, data storage, and bus interface circuits. Its robust design and ON Semiconductor's commitment to quality make it an excellent choice for designers looking to incorporate reliable flip-flops in their digital logic systems.
