SN74LS194AN (74LS194) register
Description:
The SN74LS194AN is a 4-bit bidirectional universal shift register IC, capable of shifting data in both directions (left and right) based on control inputs. It features a parallel load capability where data can be loaded into the register asynchronously. This IC is commonly used in digital systems for various applications such as data storage, serial-to-parallel conversion, parallel-to-serial conversion, and arithmetic operations involving shifts.
