Logic - Latches are a type of memory circuit used to store a single bit of digital information either zero or one. This information is held inside the latch until it is clocked, and then can be changed using the same clock signal. Examples of latch use include the preservation and recall of input or output states, or the conditional interrupting and disabling of a machine cycle. The SN74ABT16841DL is a type of Logic - Latches. This article will explain the field of application and the working principle of the SN74ABT16841DL.

SN74ABT16841DL Application Field

The SN74ABT16841DL is an octal D-type edge-triggered flip-flop with 32-bit data capability per package. It is designed for simple memory applications with three-state outputs which can be connected directly to higher-order data buses. This device can be used in various applications, such as a control bit latch, a data latch, a shift register, a 1-of-32 line decoder, or a memory element in a computer system. It is suitable for applications requiring a minimum chip count and support of asynchronous loading, synchronous data swapping and other implementing options.

SN74ABT16841DL Working Principle

The SN74ABT16841DL uses a clocked edge-triggered flip-flop to store a single bit of digital information either 0 or 1. When the clock signal transitions from high to low, the stored value will change depending on what the input signals are at that moment. The stored value is then held as long as the clock signal remains low. The device has 32 bit data capability per package which allows multiple bits to be stored and can be read out of the device in parallel.

The device consists of a clocked edge-triggered flip-flop and 8 data input buffers. The data input buffers allow the user to enable or disable the transfer of the input data to the flip-flop. The ENB input is used to enable or disable the data inputs, which will result in the data being transferred to the output. An asynchronous Clear input and 3-state outputs also give the user additional control and flexibility.

Conclusion

The SN74ABT16841DL is a type of Logic - Latches designed for simple memory applications with three-state outputs. It is suitable for applications requiring a minimum chip count and can be used as a control bit latch, a data latch, a shift register, a 1-of-32 line decoder, or a memory element in a computer system. Its working principle is based on a clocked edge-triggered flip-flop which allows a single bit of digital information to be stored and can be read out of the device in parallel using the 3-state outputs.
