Product Overview: Texas Instruments CD74HC4094E

The CD74HC4094E is a high-speed silicon-gate CMOS 8-stage shift-and-store bus register designed by Texas Instruments. This integrated circuit is engineered to deliver the high-performance characteristic of CMOS devices, including low power consumption and high noise immunity, while maintaining compatibility with TTL devices.

Featuring an 8-bit serial-in, parallel-out design, the CD74HC4094E allows for serial-to-parallel data conversion with ease. It incorporates an on-chip 3-state output stage, making it particularly suitable for driving bus lines or buffer memory address registers. The device operates on a wide voltage range from 2V to 6V, providing versatile interfacing with various logic families.

Key Features

• Logic Type: 8-Stage Shift-and-Store Bus Register
• Voltage Range: 2V to 6V operation
• High Output Current: -7.8 mA to 7.8 mA
• Propagation Delay Time: 125 ns at 2V, 30 ns at 4.5V, 24 ns at 6V
• Temperature Range: -55°C to 125°C

The device allows for serial data input via a shift register clock (CP) and a register clock (STR). The shift register clock is used to shift the data into the register, while the register clock is employed to transfer data from the shift register to the storage register. This enables the CD74HC4094E to be used in a variety of applications, including serial-to-parallel data conversion, digital control, and as a buffer for digital processing systems.

Applications

• Serial-to-parallel data conversion
• Multi-segment LED displays
• Interface and bus drivers
• Buffer memory address registers

With its robust design and functionality, the CD74HC4094E from Texas Instruments stands as a reliable choice for designers looking to implement efficient data handling and storage solutions in their digital systems. Its high noise immunity and low power requirements make it an ideal component for use across a broad spectrum of electronic applications.
