74LVT162244BDL,118

Overview

The Nexperia 74LVT162244BDL,118 is a 3.3 V 16-bit buffer/driver with 3-state outputs and integrated 30 Ohm termination resistors. It operates within a supply voltage range of 2.7 V to 3.6 V. The device features four output enables (1OE, 2OE, 3OE, 4OE), each controlling four outputs. Outputs provide +12 mA/-12 mA drive capability. Inputs are overvoltage tolerant to 5.5 V and include bus-hold circuitry. IOFF circuitry supports partial power-down mode. ESD protection exceeds 2000 V HBM and 1000 V CDM. Latch-up performance exceeds 500 mA per JESD 78 Class II Level B.

Feature Summary

• Integrated 30 Ohm series resistance in outputs eliminates the need for external termination resistors.
• Bus-hold data inputs maintain unused input states without requiring external pull-up resistors.
• IOFF circuitry disables outputs during partial power-down to prevent damaging backflow currents.
• Overvoltage tolerant inputs allow direct interfacing with 5.5 V signals while powered at 3.3 V.

Applications

• High-speed 16-bit bus interfaces
• Line driving applications requiring controlled impedance
• Systems permitting live insertion or extraction

Procurement Notes

Verify the specific ordering suffix matches the required package type. The datasheet indicates that the SSOP48 variant was removed in revision 5; confirm current availability aligns with the TSSOP48 package listed in the ordering information table. Ensure design specifications match the -40 °C to +85 °C temperature range defined for this product data sheet.

Selection Notes

Select this component when designing 3.3 V systems requiring 16-bit buffering with built-in termination. It is suitable for environments needing overvoltage tolerance up to 5.5 V on inputs. The integrated bus-hold feature simplifies PCB layout by removing external pull-ups. Verify that the 30 Ohm internal resistance meets the specific transmission line impedance requirements of the target application.

Part Context

This device belongs to the 74LVT logic family, designed for low-voltage 3.3 V applications. It functions as a high-speed buffer/driver with BiCMOS technology. The 16-bit configuration allows it to act as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It complies with JEDEC standard JESD8C for the 2.7 V to 3.6 V supply range.

Replacement Considerations

The datasheet notes that the 74LVT162244BDL (SSOP48) version was removed in revision 5. Designers previously using the SSOP48 package must transition to the TSSOP48 (SOT362-1) package option available for the 74LVT162244B series.
