BU4015BF-E2

Shift Registers Overview

The BU4015BF-E2 is a dual 4-bit static shift register manufactured by ROHM Semiconductor, belonging to the 4000B CMOS logic series. It features two independent circuits with D flip-flops triggered by the rising edge of the clock input and sharing a common asynchronous reset function. The device operates within a supply voltage range of 3V to 16V and supports an operating temperature from -40°C to +85°C. Key electrical parameters include a propagation delay of up to 460ns at 5V and a maximum clock frequency of 20MHz at 5V.

Shift Registers Feature Summary

• Dual circuit architecture providing two independent 4-bit static shift registers in a single package.
• Asynchronous reset capability allowing external control to clear all stage outputs to low level regardless of clock or data inputs.
• Edge-triggered operation where flip-flops respond specifically to the rising edge of the clock signal.
• High fan-out performance enabling direct drive of multiple TTL loads.

Shift Registers Applications

• Serial-to-parallel data conversion systems
• Parallel-to-serial data transmission interfaces
• Digital timing and pulse generation circuits
• General-purpose digital logic shifting operations
