CD74FCT843AM96E4

CD74FCT843AM96E4 is a high speed CMOS logic latch device that provides non-inverted data latch with complementary outputs. This is typically used in situations when it is necessary to temporarily store data. By using this device, logic level transitions can be converted from one speed domain to another.

CD74FCT843AM96E4 is an ideal device for applications where data needs to be clocked from one part of a system to another part that operates at slower speeds without the need for a clocking scheme. This device supports transmission of data from a fast-rising edge clock transition to a slow-rising edge clock transition. This is a powerful feature which provides the ability to sample data with minimal clock delay.

The device offers five different logic function variations depending on the logic states of the two control pins and the data inputs. These logic functions are emitter-coupled logic (ECL), non-inverting latches (NLL), AND gates, OR gates, and NOR gates. The device also provides high current drive capability to allow it to buffer large amounts of data and reduce power consumption.

The working principle of this latch is based on the following concept. When the device’s clock input is rising, the data is transferred from the data input to the data output for latched data. This can be illustrated by the following diagram.

The device has two control pins and two data inputs. The two control pins determine the logic function that will be applied to the data inputs. The CP pin is used to control the latch and the ST pin is used to enable data transfer. The OP pin provides the output data.

In the diagram above, when the clock input is low, the data is not clocked in and the output data is held in its previous state. When the clock input goes high, the data is clocked in and the OP pin is driven by the data input. The device has internal circuit protection to prevent accidental triggering and damage from static electricity.

As the output device, CD74FCT843AM96E4 is suitable for many applications, such as communications equipment, digital audio systems, industrial controllers, instrumentation systems and general purpose control systems. This device can be used to buffer and store data to prevent bus contention and to provide voltage translation between two clock domains. It is also used to implement memory structures and to provide address decoding.

CD74FCT843AM96E4 is a versatile logic latch device that offers high speeds, low power consumption, low static power consumption and can be used in a variety of applications.
