The Texas Instruments 9348FMQB is a 12-bit parity generator/checker, a logic function that computes or verifies odd/even parity across a 12-bit data bus. In a memory subsystem or serial link, this IC sits between the data source and the receiver, generating a parity bit on transmit and flagging errors on receive. The package is Bulk, meaning loose tubes or trays rather than tape-and-reel — typical for through-hole or large-quantity bench assembly.
RoHS status and compliance planning
The 9348FMQB is RoHS non-compliant. For a BOM that requires RoHS exemption (e.g., leaded solder in high-reliability or aerospace assembly), this part fits; for a RoHS-mandated line, a lead-free alternative must be sourced. Because the part is active, the manufacturer continues to support it with datasheet and application notes. The non-RoHS status is a design-in gate, not a supply constraint — the part is still manufacturable and orderable through authorized channels.
Sourcing and availability for the BOM line
For a 12-bit parity function in a 24-pin or 16-pin DIP/SOIC footprint, the 9348FMQB is a direct logic drop-in. Confirm the package style (Bulk implies a DIP or similar through-hole form factor) matches the board layout before committing the line.
