74LVC16245ADGG,512

Overview

The Nexperia 74LVC16245ADGG is a 16-bit bus transceiver with direction pins and 3-state outputs, housed in a 48-TSSOP package. It operates on a supply voltage of 1.2 V to 3.6 V and supports inputs up to 5.5 V. The device features two independent 8-bit transceivers with separate output enables (1OE, 2OE) and direction controls (1DIR, 2DIR). It includes IOFF circuitry for partial power-down protection and Schmitt-trigger inputs for noise tolerance.

Feature Summary

• Supports bi-directional data transfer between 3.3 V and 5 V logic environments via overvoltage tolerant inputs.
• Includes dedicated IOFF circuitry to disable outputs and prevent damaging backflow current during partial power-down states.
• Features Schmitt-trigger action at all inputs to ensure tolerance for slower input rise and fall times.

Applications

• Mixed 3.3 V and 5 V voltage translation
• Partial power-down mode operation
• Bi-directional bus driving

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact packaging and reel specifications. Ensure the component meets the required temperature range and automotive qualification standards if applicable to your design. Cross-reference the datasheet revision date to confirm the most recent electrical characteristics and pinout definitions are utilized.

Selection Notes

Select this component when designing systems requiring 16-bit bi-directional data transfer with mixed voltage domains. It is suitable for applications needing robust noise immunity through Schmitt-trigger inputs and protection against backflow currents during power-down sequences. Verify that the 48-lead TSSOP package dimensions fit the available PCB space constraints.

Part Context

This part belongs to the 74LVC family of high-speed CMOS logic devices manufactured by Nexperia. It is functionally similar to the 74LVCH16245A but lacks the integrated bus hold feature found in the LVCH variant. Both variants share identical pinouts and core functionality as 16-bit bus transceivers.

Replacement Considerations

The 74LVCH16245ADGG serves as a direct functional substitute, offering identical pinouts and performance with the addition of internal bus hold circuits on data inputs.
