74LVC16245AEV/G:55

Overview

The Nexperia 74LVC16245AEV/G:55 is a discontinued 16-bit bus transceiver with 3-state outputs. It supports a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device includes Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. Propagation delay ranges from 1.0 ns to 13.8 ns depending on voltage. It operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Supports mixed 3.3 V and 5 V environments via 5.5 V tolerant inputs
• Includes IOFF circuitry to prevent damaging backflow current during power-down
• Features Schmitt-trigger action at all inputs for tolerance of slow rise and fall times

Applications

• Mixed 3.3 V and 5 V translation applications
• Partial power-down mode operation
• Bi-directional data bus transmission

Procurement Notes

This specific part number is obsolete and no longer in production. Verify availability through secondary market channels or confirm replacement with active variants such as the 74LVC16245ADGG. Ensure compatibility with existing PCB footprints and design specifications before sourcing alternative components.

Selection Notes

Select this component only if legacy system compatibility requires the exact EV package configuration. For new designs, consider active alternatives like the ADGG variant which offers identical electrical characteristics in a TSSOP48 package. Evaluate thermal derating requirements based on the specific package type used in the application.

Part Context

The 74LVC16245A belongs to the LVC logic family, designed for low-voltage CMOS applications. This series provides high-speed performance with wide operating voltage ranges. The AEV designation refers to a specific historical packaging option that has been superseded by newer packages like TSSOP48 and TVSOP48 in current product lines.

Replacement Considerations

The 74LVC16245ADGG is a confirmed active substitute offering identical functionality in a TSSOP48 package. Verify pinout compatibility and ensure the replacement package fits the target footprint constraints.
