SN74LVC245ADWG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC245ADWG4 is an octal bus transceiver with 3-state outputs from the Texas Instruments SN74LVC245A family. It operates within a supply voltage range of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, enabling mixed-mode signal operation. The device provides a maximum propagation delay of 6.3 ns at 3.3 V and supports low-level output currents of 24 mA. It includes Ioff circuitry for partial-power-down mode and back drive protection. The component is housed in a 20-pin SOIC (DW) package and is rated for operating temperatures between -40°C and +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports asynchronous communication between data buses with bidirectional data flow controlled by a direction input.
• Features Ioff circuitry to disable outputs during power-down, preventing damaging current backflow.
• Inputs are tolerant to 5.5 V signals while operating on lower supply voltages, facilitating down voltage translation.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'G4' indicates RoHS compliance and lead-free status as per the manufacturer's documentation. Confirm the 'DW' suffix corresponds to the 20-pin Small Outline Integrated Circuit package. Ensure the procurement source provides valid traceability and authenticity guarantees for active production logic components.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal bus interfacing with mixed 3.3-V and 5-V logic levels. It is suitable for applications needing high drive capability and fast switching speeds under low voltage conditions. Consider the thermal resistance characteristics of the SOIC-20 package for heat dissipation requirements in dense layouts.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC245A series of octal bus transceivers designed for 1.65-V to 3.6-V operation. The 'G4' suffix denotes environmental compliance, specifically RoHS standards and lead-free manufacturing. The 'DW' suffix identifies the physical 20-pin SOIC package type used for surface-mount assembly.
