Product details

The Texas Instruments SN74LVCH245DW is a bus transceiver designed for bidirectional data flow between two independent buses. The 'DW' suffix indicates a wide-body SOIC-20 package, a common footprint for octal bus-interface functions in industrial control, telecom line cards, and motor-drive backplanes where signal buffering and direction control are needed between a controller and peripheral bus.

For a BOM line, this removes the supply-chain risk of a sudden discontinuation that would force a board respin. The RoHS non-compliant status is the main procurement flag: this part uses lead-bearing solder terminations, so it is exempt from RoHS restrictions for certain applications (military, aerospace, high-reliability industrial) but cannot be used in standard RoHS-compliant consumer or commercial assemblies without an exemption claim.

Sourcing posture — quoted to order

The active lifecycle means there is no urgency from an impending EOL, but the RoHS non-compliant status narrows the pool of buyers who can accept it, so lead-time variability is higher than for a fully RoHS-compliant equivalent. A procurement buyer should specify the exemption category (e.g., RoHS Annex III or IV) in the RFQ notes to avoid compliance delays.

Frequently asked questions

What is the equivalent or replacement for SN74LVCH245DW?

The SN74LVCH245DW is a bus transceiver in the LVC family. A functional equivalent within the same logic family is the SN74LVC245A, which shares the same octal bus-transceiver function and pinout but operates with slightly different input thresholds. The 74ACT16833DL is a different device class (18-bit registered transceiver) and is not a direct pin-compatible replacement. For a drop-in substitute, verify the supply voltage range and direction-control logic against your design — the LVC245A is the closest same-function peer.

Is SN74LVCH245DW compatible with 5V logic signals?

It is not rated for 5 V supply operation. However, the LVC family inputs are 5 V tolerant when the device is powered from 3.3 V, meaning a 5 V logic signal applied to an input pin will not damage the part. The output swing will be rail-to-rail up to the 3.6 V supply maximum, so a 5 V output level is not generated. For 5 V bus interfacing, a level-shifter or a 5 V-tolerant transceiver from the AHC or ABT family would be needed.
