The CD74HCT4094E is a high-speed silicon-gate CMOS 8-stage shift-and-store bus register designed by Texas Instruments. This integrated circuit is part of the HCT family, which ensures compatibility with the TTL logic levels while maintaining the low power consumption and high noise immunity of CMOS technology.

Key Features

• Logic Type: 8-Stage Shift-and-Store Bus Register
• Operating Voltage: 4.5V to 5.5V
• High-Speed Operation: Ensures quick data transfer and processing
• Typical Shift Frequency: 35 MHz
• Output Drive Capability: 15 LSTTL loads
• Temperature Range: -55°C to 125°C

Functional Description

The CD74HCT4094E device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Data is shifted on the positive-going transitions of the shift register clock input (CP) and the data in the storage register is transferred to the output buffer on a positive-going transition of the strobe input (STR). When the output enable (OE) is held high, the outputs are disabled and held in a high-impedance state. This allows for data bus interfacing in a multi-device environment.

Applications

Suitable for a wide range of applications, this device is often used in situations where it is necessary to convert serial data to parallel data, such as:

• Serial-to-parallel data conversion
• Data control systems
• Signal processing
• Input/output port expansion
• Interface between different voltage levels
