Product Description

The 74HCT273D is an advanced high-speed CMOS (Complementary Metal Oxide Semiconductor) device fabricated with silicon gate CMOS technology. It possesses the low power consumption of standard CMOS integrated circuits, along with the ability to drive 15 LSTTL (Low-Power Schottky TTL) loads. The 74HCT273D has eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. The common asynchronous Master Reset (MR) input resets all flip-flops, making the Q outputs LOW independent of the clock.

This device is packaged in a 20-pin SOIC (Small Outline Integrated Circuit), ensuring a compact footprint for space-constrained applications. The balanced propagation delay and transition times of the 74HCT273D make it ideal for use in mixed-technology environments where low power and high speed are required.

Applications

The versatility of the 74HCT273D allows it to be used in a variety of digital applications, including:

• Computing Systems
• Data Storage
• Signal Processing
• Instrumentation
• Telecommunications
• Controllers
