74LVCH322244AZKER

Overview

The Texas Instruments 74LVCH322244AZKER is a 32-bit buffer and line driver featuring non-inverting logic with three-state outputs. It operates within a supply voltage range of 1.65 V to 3.6 V, supporting low-voltage digital systems. The device utilizes a 96-pin BGA Microstar package for surface-mount installation. Key electrical characteristics include high-level output current of -24 mA and low-level output current of 24 mA. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides 32-bit buffering capability with non-inverting signal transmission
• Features three-state outputs for effective bus management and isolation
• Operates on low supply voltages ranging from 1.65 V to 3.6 V
• Designed for high-speed digital applications with defined drive strengths

Applications

• High-density data bus buffering in embedded systems
• Voltage level translation between different logic domains
• Clock distribution networks requiring precise signal integrity
• Memory interface drivers in consumer electronics

Procurement Notes

Verify the specific suffix 'ZKER' against official Texas Instruments documentation to confirm pinout and packaging details. Confirm RoHS compliance status through current manufacturer declarations. Check for obsolescence notices as this component may be discontinued or replaced by newer series variants. Ensure ESD handling protocols are followed during procurement and storage due to CMOS sensitivity.

Selection Notes

Select this component when a 32-channel non-inverting buffer is required for low-voltage logic families. Compare propagation delay specifications against system timing requirements. Evaluate the BGA Microstar footprint compatibility with existing PCB layouts. Consider thermal dissipation capabilities within the constrained package size for high-frequency operation scenarios.

Part Context

This part belongs to the LVCH (Low-Voltage CMOS High-Speed) logic family from Texas Instruments. It serves as a high-performance alternative to standard LVC devices, offering improved switching speeds while maintaining compatibility with 3.3V and 2.5V systems. The 32-bit configuration reduces board space compared to using multiple smaller buffers.

Replacement Considerations

Check for SN74LVCH32244 variants which may share similar electrical characteristics but differ in packaging or suffix codes. Verify if SN74LVC32244 or SN74ALVCH32244 parts are suitable substitutes based on voltage and speed requirements. Consult Texas Instruments replacement guides for confirmed cross-references.
