74LVT16245BDL,112

Overview

The Nexperia 74LVT16245BDL,112 is a BiCMOS 3.3 V 16-bit bus transceiver with 3-state outputs. 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 capability of +64 mA and -32 mA, ensuring direct interface with TTL levels. It includes IOFF circuitry for partial power-down mode operation and bus hold data inputs to eliminate external pull-up resistors.

Feature Summary

• BiCMOS technology providing high speed and strong output drive capabilities
• IOFF circuitry enabling partial power-down mode operation
• Bus hold data inputs eliminating the need for external pull-up resistors

Applications

• Bidirectional bus interface applications
• Systems requiring live insertion and extraction
• Interfaces between systems operating at different supply voltages

Procurement Notes

Verify the package type against the specific ordering suffix, as the datasheet revision history indicates that the DL (SSOP48) variant was removed in version 12. Confirm current availability and lead times directly with Nexperia or authorized distributors, as this component may be subject to obsolescence or discontinuation status.

Selection Notes

Select this component when a 16-bit bidirectional transceiver with high drive strength (+64 mA/-32 mA) is required. Ensure the design supports the 2.7 V to 3.6 V supply range and utilizes the bus hold feature to simplify input handling. Verify compatibility with the target system's voltage levels, particularly regarding the 5.5 V input tolerance.

Part Context

This part belongs to the 74LVT16245B family of 3.3 V 16-bit transceivers manufactured by Nexperia USA Inc. It is designed for high-performance BiCMOS applications requiring wide supply voltage ranges and robust output drive capabilities. The device is specified for industrial temperature ranges from -40 °C to +85 °C.

Replacement Considerations

Check for the 74LVTH16245BDL variant if hysteresis is required. Note that the SSOP48 package (DL) was removed in datasheet revision 12; verify if the BDGG (TSSOP48) package is an acceptable alternative.
