74LVT16244BDGG,118

Overview

The Nexperia 74LVT16244BDGG,118 is a 3.3 V 16-bit buffer and line driver featuring 3-state outputs in a TSSOP-48 package (SOT362). It operates within a supply voltage range of 2.7 V to 3.6 V. The device provides an output drive capability of +64 mA for low-level states and -32 mA for high-level states. Static characteristics include a maximum input leakage current of ±10 μA at VCC = 3.6 V. Dynamic performance specifies propagation delays between inputs and outputs ranging from 0.5 ns to 4.0 ns depending on the transition type and voltage conditions.

Feature Summary

• Features bus hold data inputs that eliminate the need for external pull-up resistors to define unused inputs.
• Includes IOFF circuitry that provides partial power-down mode operation by disabling outputs to prevent damaging backflow currents.
• Supports live insertion and extraction with no bus current loading when outputs are tied to a 5 V bus.

Applications

• High-speed 16-bit bus interface applications
• Mixed voltage environments requiring direct interface with TTL levels
• Systems requiring partial power-down capabilities

Verify the specific ordering suffix

Selection Notes

Select this component for designs requiring a 16-bit non-inverting buffer with high drive strength. Ensure the system operates within the 2.7 V to 3.6 V supply range. Consider the TSSOP-48 package constraints for PCB layout. Verify that the application benefits from the integrated bus hold feature to simplify input handling for unused lines.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage CMOS applications. It serves as a buffer/driver variant within the broader 74-series logic portfolio. The BDGG suffix indicates the TSSOP48 plastic thin shrink small outline package. It is distinct from transceiver variants like the 74LVT16245 which provide bidirectional control.

Replacement Considerations

The 74LVTH16244BDGG is a compatible alternative within the same series offering similar functionality. Other 16-bit buffers in the LVT family may serve as substitutes if pin compatibility and electrical specifications align with the design requirements.
