BU2114F-E2

Shift Registers Overview

The BU2114F-E2 is an 8-bit shift register and latch driver IC manufactured by Rohm Semiconductor. It features a CMOS configuration with low power consumption and open drain outputs capable of driving up to 36 mA per pin, with a total static drive capacity of 150 mA. The device operates within a recommended voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 5 MHz. It includes serial data input (SIN), shift clock (CK), latch control, enable, and reset functions. The component is housed in an SOP-18 package and is designed for microcomputer peripheral circuits.

Shift Registers Feature Summary

• CMOS architecture providing low power consumption
• Open drain outputs supporting high current drive capabilities
• Asynchronous latch function for 8-bit shift register data
• Supports cascade connections for expanded I/O applications

Shift Registers Applications

• Microcomputer peripheral circuits
• Industrial equipment expansion boards
• Office telephone systems
• Audio visual equipment interfaces

Shift Registers Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest documentation to confirm packaging and compliance details. Confirm that the SOP-18 package variant matches the design requirements. Check for any end-of-life or not recommended for new design statuses directly from official Rohm channels before finalizing procurement plans.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel converter with high-current open-drain outputs is required. Ensure the system voltage aligns with the 4.5 V to 5.5 V operating range. Consider the 5 MHz maximum clock speed for timing constraints. Verify that the open-drain output topology suits the load interface, as external pull-up resistors are necessary for proper logic high levels.

Shift Registers Part Context

This part belongs to the BU2114 series of standard CMOS shift register and latch drivers. It is functionally similar to the BU2114 but distinguished by its SOP-18 surface-mount package compared to the DIP-18 variant. The series is designed for general-purpose digital expansion tasks in consumer and industrial electronics.

Shift Registers Replacement Considerations

The BU2114 serves as a direct functional equivalent with identical electrical characteristics, differing only in the DIP-18 package format. Other BU211x family members may offer different bit depths or package options.
