ON Semiconductor MC74HCT273ADTR2G Octal D-Type Flip-Flop

The MC74HCT273ADTR2G from ON Semiconductor is a high-performance, octal D-type flip-flop with a clear function, designed to operate at a voltage range of 4.5V to 5.5V. This integrated circuit is a member of the high-speed CMOS family and is TTL-compatible, allowing for easy interfacing with standard logic families. The device is packaged in a TSSOP-20 configuration, providing a compact solution for space-constrained applications.

Each flip-flop in the MC74HCT273ADTR2G is positive-edge triggered, meaning that the logic state on the D input is transferred to the Q output on the rising edge of the clock pulse. The clear input is asynchronous, allowing the user to reset all flip-flops to a low level regardless of the clock input, ensuring a predictable initialization state for all outputs upon power-up or during operation.

Key features of the MC74HCT273ADTR2G include its high noise immunity, which is characteristic of CMOS devices, and its low power consumption, making it suitable for battery-powered and energy-efficient designs. The device also boasts a high-fanout capability, allowing it to drive multiple inputs without the need for additional buffering.

Typical applications for the MC74HCT273ADTR2G include:

• Data storage and retrieval systems
• Shift registers and counters
• Control registers
• System state storage

With its robust latch-up performance, the MC74HCT273ADTR2G is able to withstand high-energy pulses, making it reliable in harsh electrical environments. Additionally, its ESD tolerance ensures the device's integrity during handling and operation.

ON Semiconductor's commitment to quality is reflected in the MC74HCT273ADTR2G's compliance with the stringent requirements of the RoHS directive, making it a suitable choice for environmentally conscious applications that require lead-free components.

Overall, the MC74HCT273ADTR2G is a versatile and reliable component for designers looking to implement precise timing and control in their digital circuits, with the added benefits of low power consumption and high integration.
