74LVT162244ADGGRE4

Overview

The SN74LVT162244ADGGRE4 is a 3.3-V ABT (Advanced BJT Technology) 16-bit buffer and driver featuring 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and supports an operating temperature range from -40°C to +85°C. The device utilizes a 48-pin TSSOP package with a lead-free RoHS-compliant construction. Key electrical characteristics include a propagation delay of 3.4 ns at 3.3 V, high-level output current of -12 mA, and low-level output current of 12 mA. Static current is specified at 5 mA, while the operating supply current is 5 µA.

Feature Summary

• Provides non-inverting buffering for 16 input lines to 16 output lines
• Features 3-state outputs for effective bus line driving and isolation
• Utilizes Advanced BJT Technology (ABT) for optimized performance

Applications

• High-speed data bus buffering in computer systems
• Memory module interface drivers
• General-purpose 16-bit parallel data transmission

Procurement Notes

Verify the complete part number including the suffix 'E4' to confirm lead-free status and RoHS compliance as per manufacturer specifications. Ensure the ordering code matches the specific tape-and-reel packaging configuration required for surface-mount assembly processes. Cross-reference the datasheet revision date to confirm technical parameters align with current design requirements.

Selection Notes

Select this component when a 3.3-V logic family solution is required for 16-bit wide data paths. The ABT technology offers faster switching speeds compared to standard LVC or LVTH families. Consider the TSSOP-48 package dimensions for PCB layout constraints and verify that the 3.3-V supply rail is stable within the 2.7-V to 3.6-V operational window.

Part Context

This device belongs to the SN74LVT162244A series of buffers and line drivers. It is functionally similar to other 16-bit ABT buffers like the SN74LVTH162244 but distinguished by its specific logic family designation and manufacturing revisions. The 'E4' suffix indicates environmental compliance features defined by Texas Instruments for this specific production batch.

Replacement Considerations

Direct pin-compatible substitutes within the same logic family include the SN74LVTH162244ADGGR. Verify voltage levels and drive strength specifications before substituting with devices from different logic families such as ALVC or LVC.
