Logic - Shift Registers

The HEF4894BT-Q100,118 is a logic register that is used in a variety of applications. It is designed to store and transmit data in a specific sequence. The device is used in circuits that require the same data flow to be sent repeatedly. The register is also known as a serial-in parallel-out (SIPO) logic register. The HEF4894BT-Q100,118 has four sections, each containing three stages. The first stage is input data, the second stage is hold data and the third stage enables the shift capability. The total number of bits in the register is equal to the number of stages times the number of sections. As previously mentioned, this device has three sections each containing three stages, resulting in nine bits. The HEF4894BT-Q100,118 is a synchronous serial-in parallel-out logic register that is commonly used in secure access control circuits, clock dividers, GPIO input/output expansion, and frequency dividers. It has a wide operating voltage range from 2.7v to 5.5v and its package is compatible with DIP-8 and SOIC-16 pads. Its current consumption is low and its power dissipation is low. It is also resistant to power surges and is not affected by electrostatic shock. The clock input of the HEF4894BT-Q100,118 is used to control the data transmission between stages. Data is transferred from the input to the output when a high-level signal is applied to the CLK input. The first three stages input data can be transferred to the output when a high-level signal is applied to the ST1 input. The second three stages data can be transferred to the output when a high-level signal is applied to the ST2 input. The output data is held until a new data is loaded or a low-level signal is applied to the CLR input. The HEF4894BT-Q100,118 logic register is versatile, reliable and efficient. It is used in a wide variety of applications such as secure access control, GPIO input/output expansion, clock dividers, and frequency dividers. It has a wide operating voltage range, is resistant to power surges, and has a low current consumption. Its package is compatible with DIP-8 and SOIC-16 pads and requires no specialized tools for installation and maintenance.
