CD74HCT299M96G4

Shift Registers Overview

The CD74HCT299M96G4 is a high-speed CMOS logic component manufactured by Texas Instruments. It functions as an 8-bit universal shift register with bidirectional serial shifting capabilities and parallel input/output options. The device features three-state outputs for bus-driven applications. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum frequency of 16MHz at nominal supply. The unit is housed in a 20-pin SOIC package and is rated for operation across an extended temperature range from -55°C to +125°C.

Shift Registers Feature Summary

• Bidirectional serial shifting capability allows data movement in both directions through the internal register stages.
• Common I/O pins facilitate flexible configuration for parallel loading and shifting operations.
• Three-state outputs provide gated control, enabling safe connection to system buses without signal contention.

Shift Registers Applications

• Data buffering in digital communication systems
• Parallel-to-serial and serial-to-parallel conversion interfaces
• General-purpose shift register tasks in industrial control logic

Shift Registers Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS adherence when sourcing. Confirm the M96 designation corresponds to the correct 20-SOIC narrow package variant. Ensure the supplier provides official datasheets matching the Texas Instruments part number to guarantee functional equivalence and operational parameters.

Shift Registers Selection Notes

Select this component when bidirectional shifting and tri-state output isolation are required within standard HCT logic levels. It serves as a direct replacement for legacy 74HCT299 devices in designs requiring extended temperature ranges. Consider the 20-SOIC footprint constraints and verify that the 4.5V to 5.5V supply range aligns with the target system power architecture.

Shift Registers Part Context

This part belongs to the Texas Instruments CD74HCT series, which utilizes high-speed CMOS technology compatible with standard TTL logic inputs. The 299 model specifically addresses universal shifting needs, distinguishing itself from simple unidirectional registers by offering dual-directional serial access and comprehensive parallel data handling within a single integrated circuit package.

Shift Registers Replacement Considerations

The CD74HCT299M96 is a compatible alternative from Texas Instruments. Other manufacturers may offer equivalent 74HCT299 variants, but pinout and electrical specifications must be verified against the original datasheet to ensure interchangeability.
