74LVT16245BDGG,112

Overview

The Nexperia 74LVT16245BDGG,112 is a BiCMOS 3.3 V 16-bit bus transceiver with 3-state outputs housed in a 48-lead TSSOP package (SOT362-1). It operates within a supply voltage range of 2.7 V to 3.6 V and supports overvoltage tolerant inputs up to 5.5 V. The device provides an output drive capability of +64 mA and -32 mA, enabling direct interface with TTL levels. It features two independent 8-bit sections controlled by separate direction and output enable pins.

Feature Summary

• Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs
• IOFF circuitry provides partial power-down mode operation to prevent damaging backflow current
• Live insertion and extraction permitted without bus current loading when tied to a 5 V bus
• Power-up 3-state ensures high-impedance OFF-state upon initialization

Applications

• High-speed bidirectional bus interfaces
• Mixed 3.3 V and 5 V system translation
• Memory and flash memory modules

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration. Confirm the package variant corresponds to SOT362-1. Ensure compliance with RoHS3 standards and check for any recent Product Change Notifications regarding marking or assembly transfers before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high drive strength and compatibility with 5 V systems while operating at 3.3 V logic levels. The integrated bus hold feature simplifies design by removing external pull-ups. Verify that the thermal environment remains within the specified -40 °C to +85 °C operating range for optimal performance.
