Product details

Bus transceiver for bidirectional data paths

The Texas Instruments SN74F2245DBR is an octal bus transceiver designed for bidirectional asynchronous communication between two data buses. It belongs to the 74F logic family, operating at the standard 5 V supply typical of F-series devices.

Active lifecycle, RoHS constraint

For legacy builds or military/industrial contracts that explicitly allow tin-lead finish, it remains a viable, directly orderable line item.

The active lifecycle means it is still in regular production, so the channel should be able to support recurring BOM quantities without the spot-market premium that obsolete parts carry.

Frequently asked questions

What is the function of SN74F2245?

It is an octal bus transceiver that provides bidirectional data transfer between two buses, with direction controlled by a DIR input and output enable via an OE pin.

Can SN74F2245DBR replace the 74F2245?

Yes, the SN74F2245DBR is the surface-mount (SOIC) variant of the 74F2245 base part number. It is functionally identical to the through-hole or other package options in the 74F2245 family.
