BU4094BC

Shift Registers Overview

The BU4094BC is a general-purpose CMOS logic integrated circuit manufactured by ROHM Semiconductor. It functions as an 8-bit static shift/store register, integrating an 8-bit shift register and an 8-bit latch within a single silicon monolithic structure. The device accepts serial data input and provides both parallel and serial outputs. Key electrical specifications include an operating supply voltage range of 3V to 16V and an operating temperature range from -40°C to +85°C. The component supports standard DIP16, SOP16, and SSOP-B16 packages.

Shift Registers Feature Summary

• Asynchronous strobe input allows read data in the shift register to be transferred to the latch, enabling output data holding during transfer operations.
• High fan-out capability with high input impedance, allowing direct driving of two L-TTL inputs or one LS-TTL input without additional buffering.
• Low power consumption characteristics inherent to the CMOS technology used in the monolithic construction.

Shift Registers Applications

• General purpose digital logic circuits requiring serial-to-parallel conversion
• Data storage applications utilizing the asynchronous latch function
• Timing control systems using the clocked shift register mechanism

Shift Registers Procurement Notes

Verify the specific package variant required for the design, as the base model number covers DIP16, SOP16, and SSOP-B16 configurations. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range. Ensure power supply connections strictly adhere to the recommended operating conditions to prevent damage from reverse polarity or overvoltage transients.

Shift Registers Selection Notes

Select this component when an 8-bit shift and store register is needed with wide voltage tolerance. The CMOS architecture suits designs prioritizing low quiescent current. Verify interface compatibility if TTL-level signals are present, as the device can directly drive specific TTL loads. Consider thermal dissipation requirements based on the chosen package type and ambient operating conditions.

Shift Registers Part Context

This part belongs to the BU4094BC family of general-purpose CMOS logic ICs produced by ROHM Semiconductor. The series includes variants distinguished primarily by their physical packaging formats, such as the through-hole DIP16 and surface-mount SOP16 and SSOP-B16 options. All variants share identical internal circuitry and electrical performance specifications defined in the official datasheet.

Shift Registers Replacement Considerations

Direct pin-compatible replacements may exist within other manufacturers' 4000-series CMOS libraries, provided they meet the 3V to 16V supply voltage and -40°C to +85°C temperature specifications. Verify that any substitute maintains the same 8-bit shift/latch functionality and output drive capabilities before implementation.
