Product details

Bus driver in active production — what this means for your BOM

The Texas Instruments SN74LV244DWR is a BUS DRIVER — a non-inverting octal buffer and line driver designed for bus-oriented or memory-address driving applications.

RoHS status — a compliance flag to resolve

If your process mandates RoHS compliance, you will need either a waiver or an alternate part number. The SN74LV244 family includes RoHS-compliant variants (e.g., SN74LV244PWR), though the specific order code and package differ.

Sourcing posture — quoted to order

Because the part is active and non-RoHS, supply is generally stable but not always on the shelf at every distributor — the RFQ route ensures a committed price and delivery window.

Frequently asked questions

Can SN74LV244DWR be used as a replacement for SN74LV244AN?

Both are SN74LV244 octal bus drivers, so the functional logic is identical. The difference is package and shipping form — SN74LV244AN is typically in a PDIP package, while SN74LV244DWR comes in a SOIC-20 (Bulk shipping). Verify the footprint matches your board before substituting.

What is the difference between SN74LV244 and SN74LV245?

Both are octal bus transceivers, but the SN74LV244 is a buffer/driver with fixed direction (inputs on one side, outputs on the other), while the SN74LV245 includes a direction-control pin (DIR) for bidirectional data flow. Choose the 244 for unidirectional buffering and the 245 for bidirectional bus isolation.
