The SN74HC373NG4 is a high-performance, eight-bit positive-edge triggered D-type flip-flop designed with an advanced silicon-gate CMOS technology. It is an ideal choice for use as a memory device in most logic applications, including dynamic RAM and register files. The latch consists of eight D-type flip-flops with a common Clock (CP) and a common Reset (MP) input. Each flip-flop is individually addressable with its own data input (D0–D7) and output (Q0–Q7). The 74HC373NG4 is capable of operating at a frequency of up to 30MHz and produces a hold time of 8ns maximum.

Applications

The SN74HC373NG4 latch is a versatile and highly useful part for a variety of applications, ranging from microcontrollers and digital logic ICs to motion control and signal processing ICs. It is used in memory devices, including RAM, register files, and programmable logic arrays. It is also commonly used to provide memory elements in sequential logic circuits and data-processing circuits.

Features

The SN74HC373NG4 latch has several features that make it a desirable choice for many applications. It offers high speed operation, with a maximum switching frequency of 30MHz. It can also operate over a wide power supply voltage range of 2.0V to 6.0V. Additionally, it offers a hold time of 8ns, which contributes to its high reliability. The flip-flop is also very resistant to noise and has an adjustable setup and hold time.

Working Principle

The SN74HC373NG4 is a high-speed D-type flip-flop with a common Clock (CP) and Reset (MP) input. It consists of eight individually addressable flip-flops, each with its own data input (D0–D7) and output (Q0–Q7). When the Clock (CP) is pulsed low, the data on the data inputs to the parallel-to-serial shift register is shifted one bit to the serial data output (Q0–Q7). The Reset (MP) line can be used to reset the shift register, clearing all the data in the register.

The SN74HC373NG4 latch can also be used to provide an asynchronous reset for certain logic devices. When the Reset (MP) is low, the data stored in the flip-flops is reset to a known state, allowing the devices to function properly. This is useful in situations where a common reset is needed for a group of data registers.

The SN74HC373NG4 is an ideal choice for applications where reliability, speed, and low power consumption are important. It is a cost-effective solution for many logic applications, and its flexibility in use combined with its ability to provide a wide voltage range and a high switching frequency make it a viable choice for many memory applications.
