74LVC245APW,118

Overview

The Nexperia 74LVC245APW,118 is an octal bus transceiver with three-state outputs housed in a TSSOP-20 package. It operates on a supply voltage range of 1.2 V to 3.6 V and supports overvoltage tolerant inputs up to 5.5 V. The device features Schmitt-trigger action for slow input transitions and includes IOFF circuitry for partial power-down applications. Propagation delay ranges from 1.5 ns to 17.0 ns depending on voltage.

Feature Summary

• IOFF circuitry prevents damaging backflow current during partial power-down mode
• Schmitt-trigger inputs provide tolerance for slower rise and fall times
• Overvoltage tolerant inputs allow direct interfacing with 5 V devices

Applications

• Mixed 3.3 V and 5 V environment translation
• Partial power-down system designs
• Bidirectional data bus interfaces

Procurement Notes

Verify the specific suffix '118' corresponds to the TSSOP-20 package variant when sourcing. Confirm that the required application does not exceed the absolute maximum ratings defined in the official datasheet. Ensure compatibility with the specified temperature range for your operational environment before finalizing procurement.

Selection Notes

Select this component when low-power CMOS operation within the 1.2 V to 3.6 V range is required. It is suitable for designs needing robust ESD protection and high noise immunity via Schmitt triggers. Consider the TSSOP-20 footprint constraints and ensure the design accommodates the necessary direction control and output enable signals.

Part Context

This part belongs to the 74LVC245A family of octal bus transceivers manufactured by Nexperia. It shares functional similarities with other LVC series devices but is distinctively packaged in TSSOP-20. The family is designed for general-purpose bidirectional data transmission in low-voltage digital systems.

Replacement Considerations

Direct replacements include other 74LVC245 variants in TSSOP-20 packages from the same manufacturer. Verify pinout compatibility and electrical specifications against the original requirements before substitution.
