N74F299D,602

Shift Registers Overview

The N74F299D,602 is an 8-bit universal shift/storage register with 3-State outputs manufactured by NXP USA Inc. It operates within a supply voltage range of 4.5V to 5.5V and supports a commercial temperature range of 0°C to +70°C. The device features multiplexed parallel I/O for reduced pin count, additional serial inputs and outputs for expansion, and four operating modes: Shift left, shift right, load, and store. Typical maximum clock frequency is 115 MHz with a typical total supply current of 58 mA.

Shift Registers Feature Summary

• Multiplexed parallel I/O design reduces the total number of package pins required for data input and output operations.
• Includes dedicated serial inputs and outputs (Q0, Q7) to facilitate easy serial cascading for longer word expansion.
• Supports four distinct operating modes including synchronous shift left, shift right, parallel load, and hold functions.
• Features 3-State outputs controlled by active-LOW enable signals to support bus-oriented applications.

Shift Registers Applications

• Bus-oriented digital systems requiring tri-state buffering capabilities
• Serial-to-parallel and parallel-to-serial data conversion circuits
• Digital counters and shift registers in communication interfaces
• Memory storage elements in microprocessor-based systems

Shift Registers Procurement Notes

Verify the specific ordering code suffix against the manufacturer's latest documentation to confirm package type and temperature grade. Confirm availability status as distribution channels may vary. Ensure compatibility with existing system voltage levels and logic families before integration. Check for any recent product change notifications regarding manufacturing updates or end-of-life declarations.

Shift Registers Selection Notes

Select this component when an 8-bit universal shift register with tri-state outputs is required. Consider the 20-pin SOIC package for surface mount applications. Evaluate the 115 MHz typical maximum clock frequency against system timing requirements. Verify that the 4.5V to 5.5V supply voltage range aligns with the target power supply architecture.

Shift Registers Part Context
