74LVT16240ADGG,118

Overview

The Nexperia 74LVT16240ADGG,118 is a high-performance BiCMOS inverting 16-bit buffer/driver designed for VCC operation at 3.3 V. It features four output enable inputs (1OE, 2OE, 3OE, 4OE), each controlling four of the 3-state outputs. The device supports TTL input and output switching levels and provides interface capability to systems at 5 V supply. It includes bus-hold data inputs to eliminate external pull-up resistors and offers power-up 3-state functionality.

Feature Summary

• Features four independent output enable inputs to control groups of 3-state outputs.
• Includes bus-hold data inputs that eliminate the need for external pull-up resistors on unused inputs.
• Provides power-up 3-state functionality to prevent initial bus loading.
• Supports live insertion and extraction without causing bus current loading when tied to a 5 V bus.

Applications

• Driving bus lines in 3.3 V digital systems
• Interfacing between 3.3 V devices and 5 V systems
• Applications requiring live insertion or extraction

Procurement Notes

Verify the specific package variant SOT362-1 (TSSOP48) matches the design footprint. Confirm the operating temperature range requirement aligns with the -40 °C to +85 °C specification. Ensure the 3.3 V supply voltage is stable within the recommended 2.7 V to 3.6 V limits. Check for any specific ESD protection requirements regarding HBM and CDM ratings during handling.

Selection Notes

Select this component for applications requiring a 16-bit inverting buffer with 3-state outputs. It is suitable for driving bus lines where TTL compatibility is needed. Consider its ability to interface with 5 V systems while operating at 3.3 V. The bus-hold feature simplifies design by removing the need for external pull-ups on unused inputs.

Part Context

This part belongs to the 74LVT series, which utilizes Low-Voltage BiCMOS Technology. It is categorized as a buffer and line driver within Nexperia's logic portfolio. The device is manufactured in a TSSOP48 plastic thin shrink small outline package, providing a compact solution for high-density PCB designs.

Replacement Considerations

Consult official Nexperia documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully before substitution.
