SN74LV245ATPW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ATPW is an octal bus transceiver manufactured by Texas Instruments, featuring three-state outputs and bidirectional data flow control. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a TSSOP-20 surface-mount package. The device provides low output drive capability with a maximum low-level output current of 32 mA and a high-level output current of -16 mA at 5 V. Propagation delay is specified at 9.5 ns under 5 V conditions, supporting static currents as low as 2 uA. It functions reliably across an industrial temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the full part number with authorized distributors to validate authenticity and traceability before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust octal data buffering between buses operating at 5 V logic levels. Consider the TSSOP-20 package constraints for PCB layout and thermal management. Evaluate the propagation delay and drive strength against system timing requirements to ensure signal integrity during bidirectional transfers.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the LV (Low-Voltage CMOS) logic family, designed for high-speed operations with reduced power consumption compared to older standards. The 'A' designation typically indicates an advanced version or specific manufacturing lot characteristics defined by Texas Instruments. The 'TPW' suffix identifies the specific TSSOP-20 physical package configuration used for surface-mount assembly.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Consult the official SN74LV245 datasheet for direct pin-compatible alternatives within the same logic family. Verify that any substitute maintains identical voltage ranges, package dimensions, and electrical characteristics such as propagation delay and output drive current.
