Product Overview: 74HC174D,653 by NXP Semiconductors

The 74HC174D,653 is a high-speed Si-gate CMOS device from NXP Semiconductors, renowned for its robust performance and reliability. This particular integrated circuit is part of the 74HC/HCT series, which are known for their compatibility with TTL (Transistor-Transistor Logic) levels. The 74HC174D,653 is designed to deliver the quintessential functionality of a hex D-type flip-flop with a clear input.

The 74HC174D,653 features six D-type flip-flops with direct clear inputs. Each flip-flop has an individual clear input (nCLR) and data input (nD) as well as a single clock input (nCP). When the clock input is on a rising edge, the state of the D-type flip-flop changes to reflect the state present at the data input. However, if the clear input is taken low, the Q output is immediately driven low, irrespective of the clock or data inputs.

This device is capable of operating across a wide voltage range, from 2 V to 6 V, making it versatile for interfacing with other logic families. The propagation delay remains low even at maximum voltage, ensuring swift response times for high-speed applications. The 74HC174D,653 comes in a standard SOIC-16 package, which is suitable for surface mounting, and it supports a wide operating temperature range, making it reliable for use in various environmental conditions.

With its robust design and high functionality, the 74HC174D,653 is an excellent choice for applications requiring flip-flops with clear function, such as in registers, counters, and control circuits. Its compatibility with TTL levels also allows for easy integration into mixed-technology systems.
