74LVC16245ADL,112

Overview

The Nexperia 74LVC16245ADL,112 is a 16-bit bus transceiver with 3-state outputs. It supports operation as two 8-bit or one 16-bit transceiver. The device features dual output enables (1OE, 2OE) and direction control inputs (1DIR, 2DIR). Inputs are overvoltage tolerant to 5.5 V, enabling translation between mixed 3.3 V and 5 V environments. Schmitt-trigger inputs handle slow signal transitions. IOFF circuitry prevents backflow current during partial power-down. Operating voltage ranges from 1.2 V to 3.6 V. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Overvoltage tolerant inputs up to 5.5 V for mixed-voltage system interfacing.
• IOFF circuitry disables outputs to prevent damaging backflow current during power-down.
• Schmitt-trigger action at all inputs ensures tolerance for slower rise and fall times.
• Dual output enables and direction controls allow independent 8-bit or combined 16-bit operation.

Applications

• Mixed 3.3 V and 5 V environment translators.
• Partial power-down applications requiring backflow prevention.
• Systems utilizing TTL level direct interfaces.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation. The 'DL' suffix indicates an SSOP48 package which was removed from the standard product data sheet in revision 14. Confirm current production status and availability directly with Nexperia or authorized distributors, as this specific variant may be obsolete or superseded by other package options like TSSOP48 or TVSOP48.

Selection Notes

Select this component when bidirectional level shifting between 1.2 V and 5.5 V domains is required. Ensure the application utilizes the 3-state outputs correctly via the OE pins. Verify that the input transition rates comply with the specified limits for the chosen supply voltage. Consider the package constraints if the SSOP48 form factor is mandatory for the PCB layout.

Part Context

This device belongs to the 74LVC/LVCH family of logic components designed for low-voltage CMOS applications. It provides high-speed data transmission capabilities with robust noise immunity. The architecture follows standard MULTIBYTE flow-through pin-out conventions, facilitating easy integration into existing digital bus structures without complex rewiring.

Replacement Considerations

Check for 74LVC16245ADGG or 74LVCH16245ADGG equivalents if the SSOP48 package is unavailable. Verify functional compatibility regarding pinout and electrical characteristics before substitution.
