ON Semiconductor MC74HC273ADW Octal D Flip-Flop

The MC74HC273ADW from ON Semiconductor is a high-performance, octal D-type flip-flop integrated circuit, designed to operate as a memory storage device. It features eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. The flip-flops are designed to store the data on the D inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CLK) transition.

This device is fabricated with high-speed silicon gate technology, which ensures reduced power consumption and greater speed performance compared to conventional devices. The MC74HC273ADW is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers in a wide range of digital applications.

The MC74HC273ADW offers a common clock (CLK) and a common master reset (MR) input. The master reset input is active HIGH and, when asserted, clears all flip-flops, forcing all Q outputs LOW, regardless of the state of the clock input. This feature allows for synchronous reset capability, which is essential for managing and controlling complex digital systems.

The device operates over a broad voltage range from 2V to 6V and can interface with standard CMOS outputs, as well as with LSTTL (Low-power Schottky TTL) outputs. This makes it highly versatile for mixed-voltage applications. Additionally, its outputs can drive up to 10 LSTTL loads, providing good signal integrity.

The MC74HC273ADW is available in a wide body SOIC-20 package, which makes it easy to integrate into surface-mount technology (SMT) manufacturing processes. Its compact size and the ability to operate at a wide range of temperatures, from -55°C to +125°C, make it a reliable choice for industrial and automotive applications that require robust performance in harsh environments.

With its combination of high-speed performance, low power consumption, and wide operating voltage range, the ON Semiconductor MC74HC273ADW is an excellent choice for designers looking for a reliable and efficient octal D flip-flop for their digital systems.
