SN74AHCT373DWR Application Field and Working Principle

The SN74AHCT373DWR is a high-speed memory latch that provides outstanding system performance and fast data transfer capabilities. It is a type of latch most commonly used in applications such as bus inversion, enabling external address decoding, and as an octal memory latch.

The SN74AHCT373DWR is part of the Latch family which includes devices such as D latch, JK latch and Master-Slave flipflop. This device achieves data transfer and enable functions at the high speed of 12.5MHz.

Application Field

The SN74AHCT373DWR can be used in various medical, industrial & consumer electronics and provides high-speed memory transfers. Additionally, it is often used as octal memory latches for applications such as bus inversion, enabling external address decoding as well as data transfer and enable functions.

It is also used to latch data temporarily in systems such as VCRs. The SN74AHCT373DWR should be applied in the following areas when a high-speed memory latch is needed but without the complexity and cost associated with parallel logic.

• Data bus inversion and data transfer registers
• Interrupt controllers
• On-board memory systems
• Process control systems
• Computer buses
• ADC/DAC interfaces

Working Principle

The SN74AHCT373DWR consists of eight D-type latches. These D-type latches have three terminal connections; data input, data output and input enable. Data is transferred on the rising or falling edge of the Connect# (disable pin) signal.

When the Connect# signal is low, the input data is sent from the Data Input to the Data Output and is held until the Connect# signal goes high. The SN74AHCT373DWR is designed to work in a wide voltage range from 3.3V to 5V though only one voltage should be applied at a time. It also features two additional features over other latches which are noise immunity and static power dissipation.

The SN74AHCT373DWR has noise immunity which helps reduce noise on the data bus and static power dissipation which helps reduce power consumption in the system. This device can also be used in clock-driven data acquisition systems which require fast data-sampling capabilities.

In conclusion, the SN74AHCT373DWR offers an ideal solution for high-speed memory transmissions, since it offers high-speed data transfer and is capable of achieving fast performances with minimal power consumption. It can be used in various applications such as bus inversion, data transfer and enable functions, as well as a variety of on-board memory systems.
