74LVT16245BEV,157

Overview

The 74LVT16245BEV,157 is a 3.3 V 16-bit bidirectional bus transceiver with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 2.7 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device provides an output drive capability of +64 mA and -32 mA. It includes two output enables (1OE and 2OE) and two direction control inputs (1DIR and 2DIR). Bus hold data inputs eliminate the need for external pull-up resistors. The component complies with JEDEC standard JESD8C and supports live insertion and extraction.

Feature Summary

• Features BiCMOS high-speed technology with strong output drive capabilities.
• Includes IOFF circuitry to support partial power-down mode operation.
• Provides bus hold functionality to maintain unused input states without external components.
• Offers ESD protection exceeding 2000 V via HBM and 1000 V via CDM.

Applications

• High-speed data transmission on 3.3 V buses
• Memory and flash memory interfaces
• Clock drivers and buffering

Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape/reel configuration. Confirm the manufacturer is Nexperia, as NXP USA Inc. may distribute products originally developed under the NXP brand. Ensure the datasheet revision aligns with current production specifications before finalizing procurement orders.

Selection Notes

Select this component when interfacing between 3.3 V logic systems and 5 V tolerant peripherals. The wide supply voltage range accommodates variations in system power rails. The dual enable and direction controls allow flexible partitioning of the 16-bit bus into two independent 8-bit channels.

Part Context

This part belongs to the 74LVT/LVTH16245B family of 16-bit bus transceivers. It utilizes a TSSOP48 plastic thin shrink small outline package (SOT362-1). The device is designed for general-purpose applications requiring robust signal integrity and low power consumption during standby modes.

Replacement Considerations

The 74LVTH16245BDGG serves as a functional equivalent within the same product family. Verify pin compatibility and electrical characteristics against the original design requirements before substitution.

FAQ

How does the device handle unused inputs?

The device incorporates bus hold data inputs which actively hold unused inputs at a defined logic level, eliminating the requirement for external pull-up resistors.

Is the device suitable for hot swapping?

Yes, the device permits live insertion and extraction operations due to its specific internal circuitry design.
