ON Semiconductor MC74HC273ANG Octal D-Type Flip-Flop

The MC74HC273ANG is a high-performance, octal D-type flip-flop with a clear function, designed and manufactured by ON Semiconductor. This integrated circuit is part of the high-speed CMOS family and is fabricated with silicon gate CMOS technology to achieve operating speeds similar to LSTTL, with the low power consumption of standard CMOS integrated circuits.

This device consists of eight edge-triggered flip-flops with individual D-type inputs and Q outputs. The common buffered Clock (CP) and Master Reset (MR) inputs load and reset all flip-flops simultaneously. The MC74HC273ANG is designed to be used in applications requiring the capture and retention of multiple bits of data, such as registers, counters, and memory devices in digital systems.

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 (CP) transition. A LOW on the MR line will reset all flip-flops, regardless of the Clock input. This provides a convenient way of clearing the system with a single control signal. Furthermore, because the MR input is buffered, it can be driven with long lines or slow-rising signals without affecting the flip-flop operation.

The MC74HC273ANG is provided in a 20-pin DIP (Dual In-line Package), making it suitable for breadboard prototyping and production PCBs alike. It operates over a broad voltage range of 2V to 6V and offers a balanced propagation delay and transition times, which is beneficial for reliable, high-speed operation.

Key features of the MC74HC273ANG include:

• High-speed CMOS technology
• Eight D-type flip-flops with clear
• Operating voltage range from 2V to 6V
• Low power consumption
• Edge-triggered from a LOW to HIGH transition
• Buffered inputs and outputs
• Standard pin configuration
• ESD performance: HBM > 2000V; Machine Model > 200V

This device is ideal for interfacing with the output of microprocessors and microcontrollers where a byte-wide buffer or storage element with a clear function is required. The MC74HC273ANG is a versatile component that ensures high-speed data storage and retrieval, making it an excellent choice for a wide range of digital applications.
