ON Semiconductor MC74HC374ANG Octal D-Type Flip-Flop

The MC74HC374ANG is a high-performance, octal D-type flip-flop with a clear function, designed and manufactured by ON Semiconductor. This integrated circuit (IC) is part of the high-speed CMOS family and is ideal for use in a wide range of applications, from industrial to commercial, where a reliable and efficient edge-triggered data storage device is required.

Constructed with an advanced silicon-gate CMOS technology, the MC74HC374ANG offers the inherent benefits of low power dissipation and high noise immunity characteristic of CMOS circuitry, while also providing a significant upgrade in speed over its LS-TTL counterparts. The device consists of eight edge-triggered flip-flops with individual D-type inputs and 3-state true outputs. The 3-state outputs are designed for bus-oriented applications, allowing for direct connection to the bus line without the need for pull-up resistors.

The flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CLK) transition. A LOW on the clear input (CLR) will set all the outputs to LOW independent of the other inputs. The outputs, which are designed to drive 15 LS-TTL loads, are also capable of driving up to 15 HC-TTL loads and are in the high-impedance state when the output enable (OE) is HIGH.

Key features of the MC74HC374ANG include:

• Typical clock frequency of 50MHz
• Wide operating voltage range of 2V to 6V
• Low input current of 1µA maximum
• Low quiescent supply current of 80µA maximum (when the outputs are disabled)
• Output drive capability of 15 LS-TTL loads
• Pin and function compatible with LS-TTL counterparts
• ESD performance: HBM > 2000V; MM > 200V

Available in a 20-lead DIP package, the MC74HC374ANG is not only robust but also easy to integrate into various digital systems. It is a perfect choice for applications requiring high-speed data storage, data buffering, or where the bus line requires isolation during certain phases of operation.

ON Semiconductor is known for its commitment to high-quality components, and the MC74HC374ANG is no exception. It is a reliable and versatile choice for designers looking to enhance the performance of their digital systems with a state-of-the-art flip-flop solution.
