DM74LS161AN

The IC component DM74LS161AN is a synchronous 4-bit binary counter with parallel load. It is commonly used in electronic circuits to perform counting operations. The following are the key features and an overview of this component: 1. Overview: The DM74LS161AN is designed to count in binary sequence from 0 to 15 (binary representation) or 0 to 9 (decimal representation). It can be loaded with any desired initial count value via the parallel data inputs. The IC operates synchronously, meaning the counting and other operations are driven by clock signals. 2. Parallel Load: One of the significant features of this component is its ability to be loaded in parallel. This means that the initial count value can be directly set by providing the desired binary input through the parallel data inputs (D0, D1, D2, and D3). The LOAD input, when enabled, loads this parallel data into the counter. 3. Clear Input: The clear input (CLR) allows for the immediate clearing or resetting of the counter to a defined initial state. When this input is activated, the outputs of the counter are set to zero. 4. Count Enable Inputs: The DM74LS161AN has two count enable inputs - ENP (Enable Positive) and ENT (Enable Negative). These inputs control the counting operation. Depending on the input signal applied, the counter can be enabled to count up or disabled from counting
