CD74HC534E Octal D-Type Flip-Flop by Texas Instruments

The CD74HC534E is a high-speed CMOS logic octal D-type flip-flop with a clear feature, designed and manufactured by the renowned electronics company, Texas Instruments. This integrated circuit (IC) is part of the HC family, which is well-known for combining the high noise immunity of CMOS with the speed of TTL circuits.

The device is characterized by its eight edge-triggered flip-flops with individual D-type inputs and 3-state true outputs. The 3-state outputs are designed for bus-oriented applications. The flip-flop will store the state of their individual D-input that meets the set-up and hold time requirements on the LOW-to-HIGH clock (CLK) transition. With a wide operating voltage range from 2V to 6V, the CD74HC534E is versatile for interfacing with various logic levels and is compatible with standard CMOS outputs.

A noteworthy feature of the CD74HC534E is its clear (CLR) input, which, when taken to a high level, forces all outputs to the low state, overriding any other input condition. This is particularly useful in reset or initialization procedures where a known starting state is required. The clear function is asynchronous, meaning it can be activated regardless of the clock input and does not require a clock transition.

The device is encapsulated in a standard 20-pin DIP (Dual In-line Package), making it suitable for through-hole PCB mounting, which is ideal for hobbyists, educational environments, or prototyping purposes. Furthermore, it is also available in other package options to suit various application requirements.

With its low power consumption and high noise immunity, the CD74HC534E is an excellent choice for use in a wide range of applications such as memory address latching, data storage, data transferring, and as a buffer for bidirectional bus systems. Its robustness and reliability are what engineers have come to expect from Texas Instruments, a brand synonymous with quality in the semiconductor industry.
