ON Semiconductor MC74HC574ADTR2G Octal D-Type Flip-Flop with 3-State Outputs

The MC74HC574ADTR2G is a high-performance, octal D-type flip-flop integrated circuit from ON Semiconductor, designed for use in a wide range of digital applications. This device features eight edge-triggered flip-flops with individual D-type inputs and 3-state outputs, all packaged neatly in a TSSOP-20 configuration. The 3-state outputs allow for connection to a bus-structured system, providing both high drive capability and the ability to go into a high impedance state, effectively disconnecting the output from the circuit.

Constructed using the high-speed silicon-gate CMOS technology, the MC74HC574ADTR2G offers the inherent benefits of low power dissipation and high noise immunity characteristic of CMOS integrated circuits, along with the ability to interface with LSTTL logic levels. This makes it a versatile choice for interfacing with different logic families in a system.

The device features a common clock (CP) and an output enable (OE) input. 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 (CP) transition. Meanwhile, the OE input can be used to place the eight outputs in either a normal logic state or the high-impedance state. When OE is high, the outputs are in a high-impedance state, which is neither logic high nor low.

With its wide operating voltage range of 2V to 6V and the capability to directly drive up to 15 LSTTL loads, the MC74HC574ADTR2G is suitable for a variety of applications, including buffer storage, memory address registers, and data storage. Furthermore, it is compatible with the JEDEC standard no. 7A requirements, ensuring reliability and industry-standard performance.

ON Semiconductor's commitment to quality is evident in the MC74HC574ADTR2G, which is designed for optimal performance in a compact, surface-mount package. Whether used in complex microprocessors, digital signal processing, or general-purpose data storage, this flip-flop provides a reliable and efficient solution for your digital logic needs.
