STMicroelectronics HCF4094BT 8-Stage Shift-and-Store Bus Register

The HCF4094BT is a high-performance, integrated circuit designed by STMicroelectronics, a leader in the semiconductor industry. This device is an 8-stage shift-and-store bus register with a wide range of applications in the fields of digital electronics and microprocessor systems. It is especially suitable for interface applications that require a serial-to-parallel data conversion.

The HCF4094BT operates over a voltage range of 3V to 15V, making it versatile for use in various electronic systems. It is a monolithic integrated circuit, fabricated in silicon gate C2MOS technology, ensuring reliable operation and a long service life. This technology offers the advantages of high speed, low power dissipation, and reduced noise levels, which are critical for modern electronic devices.

The device features an 8-bit serial-in, parallel-out shift register that allows for the serial input of data, which can then be retrieved in a parallel format. The shift register is accompanied by a storage register and control gating that manage the transfer of data within the device, including a strobe input that allows for the storage of the data in the output register independent of the state of the clock.

The outputs of the HCF4094BT are capable of driving high-current loads, and the device includes a 3-state output stage for each bit, which allows for direct drive of data lines in bus-organized systems. The 3-state outputs also facilitate the connection of multiple registers in parallel, expanding the system's capabilities without the need for additional buffering.

The HCF4094BT is available in a 16-pin SO package, making it compact and suitable for space-constrained applications. Its high noise immunity and low power consumption make it an excellent choice for portable electronics, as well as for more complex systems requiring a robust and reliable data storage and transfer solution.

Whether used in microprocessor expansion, remote control systems, or data acquisition systems, the STMicroelectronics HCF4094BT offers designers a flexible and efficient way to manage digital data flows within their applications.
