Logic latches are digital circuits that store data in the form of multiple bits and are used to temporarily store the state of various signals in digital circuits. One such type of latch is the SN74AHC373DWR, which is an octal, dual-d-type transparent latch. It is designed to be used with a 5.0 V power supply and is characterized for making high voltage CMOS (HVCMOS) paths.

The SN74AHC373DWR is composed of two, four-bit d-type transparent latches. Each latch contains four bits of data and two separate control signals. It is a level sensitive device, which means that when the input signals reach a certain level, the output is triggered. The two control signals are a clock signal (CLK) and a latch enable (LE). When the LE signal is at a high level, the latch is enabled and the data present at the data inputs (D) at the time of the rising clock edge is stored in the latch. When LE is at a low level, the latch is disabled, the outputs are held in a high-impedance state, and the output signals are unaffected by the inputs.

The SN74AHC373DWR has multiple advantages over other types of logic latches. It is a low power device (typical power supply is 5.0 V) and has a high output drive capability up to 24 mA. It is also a fast device, with a clock to output delay of 8 ns and a setup time of 2 ns. This latch is suitable for both low and high-voltage CMOS applications and it is available in the small packaging size of 20-pin wide-body SOIC (Small Outline Integrated Circuit).

The SN74AHC373DWR uses two separate control signals to latch the data; one is the Latch Enable (LE) and the other is the Clock (CLK) signal. The LE signal acts like a gate and when it is down, the latch does not respond to any changes on the input side and so the outputs remain fixed. When LE is up, the latch responds to the CLK signal and results in its outputs changing in synchrony with its inputs. As soon as the clock signal goes high, the data present at the inputs of the latch is transferred to the outputs. This process keeps repeating as the LE is held high and the CLK pulses go high and low in a sequential manner.

The SN74AHC373DWR has many applications in the fields of instrumentation, medical imaging, consumer electronics, and data communications. It is used in low-voltage indication modules, audio/video signal processing systems, and in data communication systems. It is used in systems that require the storage of multiple bits of data such as in telecommunication systems and in digital signal processing.

The SN74AHC373DWR is an octal, dual-d-type transparent latch designed for low power, high speed, and CMOS applications. It is composed of two four-bit d-type transparent latches and uses clock and latch enable signals to latch data. This latch has many advantages, including a low power supply, high output drive capability, and fast clock to output delay time. It is suitable for low and high-voltage CMOS applications and is found in many different applications, such as instrumentation, medical imaging, consumer electronics, and data communication systems.
