SN74ALS299N

Shift Registers Overview

The SN74ALS299N is an 8-bit universal shift and storage register manufactured by Texas Instruments in the ALS logic family. It features tri-state outputs for bus-driven applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports input/output compatibility with TTL logic levels. It is housed in a 20-pin DIP package and functions across an operating temperature range of 0°C to +70°C.

Shift Registers Feature Summary

• Universal shift and storage functionality supporting serial and parallel data operations
• Tri-state outputs enabling direct connection to system buses
• Advanced Low-Power Schottky (ALS) bipolar technology for reduced power consumption

Shift Registers Applications

• Data buffering in digital systems
• Serial-to-parallel and parallel-to-serial conversion
• Shift register implementations in microprocessor interfaces

Shift Registers Procurement Notes

Verify the specific suffix 'N' confirms the 20-pin PDIP package variant. Confirm RoHS compliance status through official manufacturer documentation, as historical versions may differ. Ensure the ordering part number matches the required pin configuration and package style for your PCB layout.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with tri-state capability is required. The ALS series offers a balance of speed and low power dissipation compared to standard 74LS devices. Verify that the 20-pin DIP package fits the assembly constraints and that the 4.5V to 5.5V supply range aligns with the system design.

Shift Registers Part Context

This component belongs to the Texas Instruments SN74ALSxx series, which utilizes Advanced Low-Power Schottky technology. This family provides faster switching speeds and lower power consumption than the legacy 74LS series while maintaining pinout compatibility with standard 74xx logic families.

Shift Registers Replacement Considerations

Compatible substitutes include other 8-bit universal shift registers with tri-state outputs from the same logic family or equivalent parts from other manufacturers offering identical pinouts and electrical characteristics.
