74LVT16245BDL,118

Overview

The 74LVT16245BDL,118 is a 3.3 V 16-bit bidirectional bus transceiver with 3-state outputs manufactured by Nexperia USA Inc. 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 utilizes BiCMOS technology for high-speed performance and provides an output drive capability of +64 mA and -32 mA. It supports direct interface with TTL levels and includes bus hold data inputs to eliminate external pull-up resistors. The component is specified for ambient temperatures from -40 °C to +85 °C.

Feature Summary

• BiCMOS high speed and output drive
• Overvoltage tolerant inputs to 5.5 V
• Bus hold data inputs eliminate need for external pull-up resistors

Applications

• Bidirectional bus interface
• Mixed 3.3 V and 5 V environments
• Partial power-down applications using I_OFF circuitry

Procurement Notes

Verify the package type matches the specific design requirement, as the datasheet revision history indicates that the BDL (SSOP48) variant was removed in version 12. Confirm current availability status directly with Nexperia or authorized distributors, as ordering suffixes and package options may have changed. Ensure compliance with RoHS and REACH regulations before finalizing procurement.

Selection Notes

Select this component when a 16-bit bidirectional interface with 3-state outputs is required at 3.3 V logic levels. The device is suitable for systems needing direct TTL interfacing and overvoltage tolerance up to 5.5 V on inputs. Consider the bus hold feature if external pull-up resistors are undesirable for unused inputs. Verify that the SSOP48 package is compatible with the PCB footprint and assembly process.

Part Context

This part belongs to the 74LVT16245B family of 3.3 V 16-bit transceivers. The 'BDL' suffix historically denoted the SSOP48 plastic shrink small outline package (SOT370-1). According to datasheet revision 12, the BDL type numbers were removed, suggesting discontinuation or migration to other packages like TSSOP48 (BDGG). Check the latest product data sheet for current package offerings.

Replacement Considerations

The 74LVT16245BDGG is a functionally equivalent alternative available in the TSSOP48 package. Verify pinout compatibility and thermal characteristics when substituting between SSOP48 and TSSOP48 packages.
