HEF4094BP

The HEF4094BP is a high-performance, low-power CMOS (Complementary Metal-Oxide-Semiconductor) shift register integrated circuit produced by Philips Semiconductors, now part of NXP Semiconductors. This device is designed for various digital applications, including data storage, data transfer, and control functions in electronic systems.

Key Features:

1. Shift Register Functionality: The HEF4094BP is an 8-bit shift register, which means it can store and shift 8 bits of data. It can be used to convert parallel data into serial data and vice versa.

2. Data Input and Output: The device has a serial data input (DS) for loading data into the register and a serial data output (Q7) for retrieving the shifted data. It also features a parallel output capability, allowing access to all 8 bits simultaneously.

3. Control Pins: The HEF4094BP includes control pins such as:

   • Clock (CLK): This pin is used to synchronize the shifting of data. Each clock pulse shifts the data in the register.
   • Latch Enable (LE): This pin allows the user to latch the data present at the inputs into the register.
   • Reset (MR): This active-low pin resets the register, clearing all stored data.

4. Operating Voltage: The HEF4094BP operates over a wide voltage range, typically from 3V to 15V, making it suitable for various applications, including battery-powered devices.

5. Low Power Consumption: As a CMOS device, the HEF4094BP features low static power consumption, which is advantageous for portable and energy-efficient designs.

6. Temperature Range: The device is designed to operate within a specified temperature range, typically from -40°C to +125°C, ensuring reliability in various environmental conditions.

7. Package Type: The HEF4094BP is available in a 16-pin dual in-line package (DIP) configuration, which is suitable for through-hole mounting on printed circuit boards (PCBs). It may also be available in surface-mount packages for more compact designs.

Applications:

The HEF4094BP is widely used in applications such as:

• Data communication systems
• Microcontroller interfacing
• LED display control
• Digital signal processing
• Shift register-based data storage and retrieval systems

Summary:

In summary, the HEF4094BP from Philips Semiconductors is a versatile 8-bit CMOS shift register that provides efficient data handling capabilities in a variety of electronic applications. Its combination of low power consumption, wide operating voltage range, and robust performance makes it a popular choice among engineers and designers in the field of digital electronics.
