SN74F299NS

Shift Registers Overview

The SN74F299NS is an 8-bit universal shift and storage register from the Texas Instruments SN74F series. It operates on a single bipolar circuit within a 20-pin SOIC package. The device supports serial/parallel to serial/parallel counting sequences with asynchronous reset functionality. Electrical specifications include a supply voltage range of 4.5 V to 5.5 V, propagation delay of 11 ns, and outputs capable of three-state operation. It functions reliably across a temperature range of 0°C to +70°C.

Shift Registers Feature Summary

• Universal shift and storage capabilities supporting serial and parallel data transfer modes
• Asynchronous reset mechanism for immediate state clearing
• Three-state output drivers enabling bus line driving applications

Shift Registers Applications

• Data buffering in digital systems

Shift Registers Procurement Notes

Verify the specific suffix 'NS' indicates the standard plastic small-outline package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets the required operating temperature range for the target environment. Cross-reference pinouts with the official datasheet to prevent interface mismatches during PCB layout.

Shift Registers Selection Notes

Select this component when high-speed bipolar logic performance is required over CMOS alternatives. The SN74F series offers faster propagation delays compared to LS or HC families. Verify that the 3-state outputs align with system bus requirements. Consider the SOIC package dimensions for adequate thermal dissipation and board space constraints.
