The BU4094BCF-T1 is an 8-stage shift and store bus register manufactured by Rohm Semiconductor. This IC is commonly used for serial-to-parallel data conversion, remote control systems, display drivers, and other applications requiring data storage and parallel output. It features both serial input and parallel outputs, along with a strobe input for data transfer and an output enable for controlling the output state.

Applications

• Serial-to-parallel data conversion
• Remote control systems
• Display drivers
• Industrial control systems
• Keyboard scanners

Features

• 8-stage shift register: Stores 8 bits of data.
• Serial input and parallel outputs: Converts serial data to parallel output.
• Strobe input: Transfers data from the shift register to the output latches.
• Output enable: Controls the output state (high impedance or active).
• CMOS technology: Offers low power consumption and high noise immunity.
• Wide operating voltage range: Operates over a wide range of supply voltages.

Benefits

• Simplified data conversion: Converts serial data to parallel form for easy access.
• Reduced wiring: Serial input reduces the number of wires required for data transmission.
• Low power consumption: Extends battery life in portable applications.
• Versatile control: Strobe and output enable provide flexible control over data transfer and output state.
• Cost-effective: Offers a cost-effective solution for serial-to-parallel conversion.

Additional Details

The BU4094BCF-T1 is typically supplied in a small outline integrated circuit (SOIC) package. The device is designed for reliable operation in industrial and consumer applications. The datasheet provides detailed specifications for timing, voltage levels, and current consumption. Proper power supply decoupling is essential for stable operation. The serial data is shifted into the register on the rising or falling edge of the clock signal. The strobe input latches the data from the shift register to the parallel outputs. The output enable allows the outputs to be disabled (high impedance state) for multiplexing or other applications.
