74LVT16245BDGG,118

Overview

The Nexperia 74LVT16245BDGG,118 is a 16-bit bidirectional transceiver with 3-state outputs housed in a 48-lead TSSOP package. It operates on a single supply voltage ranging from 2.7 V to 3.6 V and features overvoltage tolerant inputs capable of handling up to 5.5 V. The device supports direct interface with TTL levels and includes bus hold data inputs to eliminate the need for external pull-up resistors. It provides an output drive capability of +64 mA and -32 mA, ensuring robust signal transmission across mixed-voltage systems.

Feature Summary

• BiCMOS high-speed technology enables rapid data transfer with low propagation delays.
• Bus hold circuitry maintains unused or floating inputs at valid logic levels without external components.
• IOFF circuitry prevents damaging backflow currents during partial power-down scenarios.
• Live insertion and extraction are permitted without causing bus current loading issues.

Applications

• High-speed data buses in computing systems
• Memory-to-memory communication interfaces
• Mixed-voltage system interconnects

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the application environment stays within the specified temperature range and voltage limits. Ensure proper ESD handling protocols are followed during assembly. Check for any recent product change notices regarding manufacturing location or material composition updates.

Selection Notes

Select this component when a 16-bit wide bidirectional interface is required between 3.3 V logic domains. The device is suitable for applications needing strong output drive capabilities and tolerance to 5 V signals on input pins. Consider the TSSOP48 package constraints for PCB layout and thermal management requirements.
