74AC299SJX

Shift Registers Overview

The onsemi 74AC299SJX is an 8-bit universal shift/storage register with common parallel I/O pins. It operates within a supply voltage range of 2.0V to 6.0V and supports temperatures from -40°C to +85°C. The device features 3-STATE outputs capable of sourcing or sinking 24mA. It includes four operating modes: shift left, shift right, load, and store. The 'X' suffix indicates availability in tape and reel packaging.

Shift Registers Feature Summary

• Common parallel I/O design reduces total package pin count by multiplexing inputs and outputs.
• Provides additional serial outputs for easy expansion and cascading of longer words.
• Features 3-STATE buffers suitable for bus-oriented applications.

Shift Registers Applications

• Bus-oriented data storage systems
• Serial-to-parallel conversion circuits
• Parallel-to-serial conversion circuits

Shift Registers Procurement Notes

Verify the specific ordering number against the manufacturer's current documentation to confirm active status and exact package variant. Ensure the required suffix matches the intended packaging format. Cross-reference electrical specifications with the latest datasheet revision to guarantee compatibility with system requirements.

Shift Registers Selection Notes

Select this component when a compact 8-bit shift register with bidirectional I/O capability is required. The AC series offers a wide voltage range compared to standard TTL logic. Consider the ACT variant if TTL-compatible input thresholds are necessary for interfacing with legacy logic families.

Shift Registers Part Context

This part belongs to the 74AC logic family, characterized by high-speed operation and low power consumption. It is functionally compatible with other 74AC devices but distinct from the 74ACT series which features TTL-compatible inputs. The SJX designation specifically identifies the SOP package variant supplied in tape and reel.

Shift Registers Replacement Considerations

The 74AC299SCM and 74AC299MTC are alternative package versions of the same logical device. For TTL-compatible input requirements, the 74ACT299 series serves as the functional equivalent within the same product line.
