SN74LVC245APWRG3

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC245APWRG3 is an octal bus transceiver with three-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, supporting mixed-mode signal operation. The device provides a maximum propagation delay of 6.3 ns at 3.3 V and includes Ioff circuitry for partial-power-down mode support. It is housed in a 20-pin TSSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports asynchronous communication between data buses with direction control via the DIR input.
• Inputs are overvoltage tolerant, accepting levels up to 5.5 V while operating at lower VCC voltages.
• Ioff circuitry disables outputs during power-down to prevent damaging backflow current.
• Provides high drive capability suitable for PCB trace length extensions and bus interface applications.

• LED displays
• Network switches
• I/O expanders

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'G3' corresponds to the required lead finish and environmental compliance status. Confirm the package type matches the design footprint requirements. Ensure the moisture sensitivity level rating aligns with the assembly process timeline. Check the RoHS status against project specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 5-V logic with 1.65-V to 3.6-V systems requiring bidirectional data transfer. The 8-channel configuration supports wide data buses. Verify that the output drive current meets the load requirements. Consider the thermal resistance characteristics if multiple devices operate in close proximity on the board.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC245A family of octal bus transceivers. It shares functional compatibility with other variants in the series but differs in packaging and manufacturing revisions. The 'PW' suffix indicates the TSSOP package style, while 'G3' denotes specific production and material attributes defined by the manufacturer.
