Overview

The PHILIPS 74HCT273D is a high-speed octal D-type flip-flop designed for reliable data storage and synchronization in digital systems. Its key operational characteristic is its ability to reliably capture data on the positive clock edge, offering a robust solution for state retention. A critical design consideration when implementing this device is managing the quiescent current draw, as the HCT family’s TTL compatibility can lead to higher standby power consumption compared to pure CMOS counterparts, particularly in designs with many unused inputs tied high.

Key Features

Octal D-type flip-flop with asynchronous master reset
Positive-edge triggered clock input
Wide operating voltage range: 4.5V to 5.5V
Low static power consumption (typical 0.01 µA)
High noise immunity due to Schmitt-trigger action on clock input
SO20 package (13.0 mm x 7.5 mm x 1.5 mm)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

Data buffering and storage in microcontrollers
Shift register implementation for serial-to-parallel conversion
State machine design for control logic
Memory address latching in embedded systems
