The MC74VHCT574ADTR2G from ON Semiconductor is a high-speed octal D-type flip-flop that is designed to meet the requirements of high-performance memory decoding or data-routing applications. This integrated circuit is characterized by its versatility and efficiency, making it an ideal choice for a wide range of digital applications.

Featuring advanced silicon-gate CMOS technology, the MC74VHCT574ADTR2G offers the high noise immunity and low power consumption you'd expect from CMOS devices, while also providing speeds similar to LSTTL parts. This combination of features ensures that the device can be used in systems that require both high-speed operation and minimal power usage.

The device has eight edge-triggered flip-flops with individual D-type inputs and 3-state true outputs. The 3-state outputs are controlled by the output enable (OE) input, which makes this device particularly well-suited for driving bus lines or buffer memory address registers. 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.

With a typical operating voltage range of 4.5V to 5.5V, the MC74VHCT574ADTR2G is compatible with TTL levels, allowing it to be used in mixed-technology environments. Furthermore, the device is offered in a TSSOP-20 package, which provides a compact footprint suitable for space-constrained applications.

Key features of the MC74VHCT574ADTR2G include:

• High-speed CMOS technology
• Typical t_pd of 8.5ns
• Low power consumption: 80µA maximum ICC
