74LVC245ADB,118

Overview

The Nexperia 74LVC245ADB,118 is an octal bus transceiver with 3-state outputs housed in a 20-lead SO plastic small outline package (SOT163-1). It operates within a supply voltage range of 1.2 V to 3.6 V and supports input voltages up to 5.5 V. The device features Schmitt trigger inputs for noise tolerance and IOFF circuitry for partial power-down applications. Propagation delay ranges from 1.5 ns to 16.9 ns depending on voltage, with output drive capabilities specified at ±24 mA.

Feature Summary

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

Applications

• Mixed 3.3 V and 5 V environment translation
• Driving bus lines
• Buffering memory address registers

Procurement Notes

Verify the specific suffix 'ADB' corresponds to the SO20 package variant when sourcing. Confirm that the required version matches the JEDEC compliance standards listed in the official datasheet. Ensure design compatibility with the specified temperature range and ESD protection levels before finalizing procurement.

Selection Notes

Select this component for designs requiring bidirectional data transfer between buses operating at different logic levels. The wide supply voltage range accommodates various low-voltage systems. Verify that the package dimensions fit the PCB layout constraints and that the thermal dissipation requirements are met for the intended operating environment.

Part Context

This part belongs to the 74LVC245A family of octal bus transceivers manufactured by Nexperia. It shares functional characteristics with other variants in the series but differs in packaging and specific electrical parameters. The device is designed for high-speed data transmission in CMOS technology, offering low power consumption and robust performance across industrial temperature ranges.

Replacement Considerations

Check for pin-compatible alternatives within the same logic family. Verify that any substitute maintains the same 3-state output capability and voltage tolerance specifications.
