74LVCH32244AEC/G:5

Overview

The 74LVCH32244AEC/G:5 is a 32-bit non-inverting buffer and line driver manufactured by Nexperia. It operates within a supply voltage range of 1.2 V to 3.6 V and features 5 V tolerant inputs and outputs, allowing direct interfacing with 5 V logic systems. The device utilizes an LFBGA-96 package (SOT536-1) and includes eight active-low output enable inputs for 3-state control. It incorporates bushold data inputs to maintain valid logic levels without external pull-up resistors. The component complies with JEDEC standards and offers ESD protection exceeding 2000 V via HBM.

Feature Summary

• Provides 32-bit buffering with 5 V tolerant I/O capabilities for mixed-voltage system integration
• Features bushold data inputs to eliminate the need for external pull-up resistors on unused lines
• Includes low inductance multiple power and ground pins to minimize noise and ground bounce
• Offers 3-state outputs controlled by eight independent active-low enable inputs

Applications

• Bus-oriented applications requiring high-performance buffering
• Mixed 3.3 V and 5 V logic environments
• Direct interface with TTL level circuits

Procurement Notes

Verify current product status as this component may be subject to discontinuation or obsolescence notices from the manufacturer. Confirm that the LFBGA-96 package availability aligns with current manufacturing schedules. Ensure compliance with RoHS directives and check for any Customer Product/Process Change Notifications (CPCN) that might affect specifications or sourcing channels before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring 32-bit wide data paths with 5 V tolerance. It is suitable for applications needing low power consumption and direct compatibility with both 3.3 V and 5 V logic families. Consider the LFBGA-96 package constraints regarding PCB layout and thermal management. Verify that the operating temperature range of -40 °C to +85 °C meets environmental requirements.

Part Context

This part belongs to the 74LVCH series of low-voltage CMOS logic devices. It is functionally similar to other 32-bit bus drivers but specifically optimized for 5 V tolerance and low power operation. The device is produced by Nexperia, formerly Philips Semiconductors, and follows standard multibyte flow-through pin-out architecture common in this logic family.

Replacement Considerations

Check for official substitute part numbers provided by Nexperia if this specific variant is unavailable. Ensure any replacement maintains the same 32-bit width, 5 V tolerance, and LFBGA-96 package footprint. Verify that functional equivalents support the required 3-state control and bushold input features.
