Logic - Latches

The MC74LCX373DWR2G is an Logic level translatable latch with octal D-type registers. It is composed of two sets of CMOS edge-triggered D-type latch cells. Each latch has eight non-inverting D-type flip-flops with individual data (D) inputs and data outputs (Q) and with complement outputs (Q). The outputs are applicable to all logic families including CMOS, TTL, Schottky, etc.

Application Field

The MC74LCX373DWR2G has a variety of applications in digital systems. It can be used for a number of tasks, such as storage registers and shift registers. Its uses range from static memory storage applications, to data switching and data transfer. In addition, it can be used to convert logic levels between two different logic families.

The device is used in circuit boards and systems that require dual operation with two different logic families. It can be used to translate data with low power losses, helping to reduce power consumption in its application.

The device is also widely used in embedded systems. It can be used to interface between the processor and the peripheral circuitry. It also provides logic level translatability and data transfer between two different logic families. This is especially useful in embedded systems as it prevents data loss when the system is switched between operating voltages.

Working Principle

The MC74LCX373DWR2G operates on the principle of an edge-triggered D-type latch. This latch has eight D-type inputs and outputs at each side. Data is transferred into the latch by applying a digital signal at the data input. When the enable signal is active, the latch output is the same as the logic input. The enable pin on each side is used to control the transfer of data (a low enable signal stops the data transfer).

The latch also provides data translatability. The device can convert logic levels from one logic family to another. For example, data from a 3.3V CMOS input can be converted to 5V TTL output. This feature helps reduce power consumption in the application.

The MC74LCX373DWR2G can be used for a variety of applications. It is a low power and low cost solution for logic level translatability between two logic families. It has been widely adopted in embedded systems, circuit boards and systems, and other areas requiring multiple logic level operations.
