ON Semiconductor MM74HCT273SJ Octal D Flip-Flop

The MM74HCT273SJ from ON Semiconductor is a high-performance, octal D-type flip-flop integrated circuit designed for use in a wide array of digital applications. This device features eight edge-triggered flip-flops with individual D-type inputs and Q outputs. The MM74HCT273SJ is particularly well-suited for employment in temporary storage, shift registers, and control and buffer registers.

Constructed with advanced silicon-gate CMOS technology, the MM74HCT273SJ offers the robustness and reliability expected from ON Semiconductor products. It boasts a high noise immunity characteristic of CMOS devices and is designed to be pin-compatible with Low Power Schottky TTL (LSTTL). This ensures that it can be used in systems that originally incorporated LSTTL logic without the need for voltage level translation.

The flip-flops in the MM74HCT273SJ are positive-edge triggered, meaning they capture data from their respective D-inputs on the rising edge of the clock signal. Once captured, the data is held at the output until the next positive edge. An additional feature of this IC is the Master Reset (MR) input, which when activated, clears all flip-flops, setting the Q outputs to a low state, regardless of clock transitions.

Key features of the MM74HCT273SJ include:

• Eight D-type flip-flops with clear
• Wide operating voltage range of 4.5V to 5.5V
• High output current: -6 mA (IOH) and 6 mA (IOL)
• Low power consumption
• Output drive capability: 10 LSTTL loads
• Typical tpd = 15 ns
• ±6 mA output drive at 5 V
• Low input current of 1 µA max
• Static flip-flop operation - retains state indefinitely with clock level either high or low

Available in a surface-mount package, the MM74HCT273SJ is designed for easy integration into a variety of PCB layouts. Its compact form factor makes it a great choice for space-constrained applications while providing the functionality necessary for complex digital systems.

Whether you are designing data storage, data transfer, or control systems, the MM74HCT273SJ from ON Semiconductor provides the performance and reliability required for your digital logic solutions.
