Device identity and logic family fit
The 74S32DC is a quad 2-input OR gate from Texas Instruments' S (Schottky) series, a TTL logic family that delivers faster switching than standard 74 series while maintaining pin compatibility with the 7400 footprint. Each of the four independent gates performs a logical OR on two inputs, making this device suitable for glue logic in legacy TTL-based control and data routing boards.
Lifecycle and compliance status
The device is RoHS non-compliant (lead-bearing), which is typical for legacy Schottky TTL parts. This is a key flag for BOMs that require RoHS conformance; the part is suited to repair, maintenance, or legacy builds where leaded solder is accepted.
Package and board integration
Supplied in Bulk format, the 74S32DC is a through-hole device (DIP-14), designed for hand assembly or wave-solder processes on boards that accommodate the 0.100-inch pitch footprint. The bulk packaging provides loose units without tape or reel, which is typical for prototyping, low-volume production, or replacement of a single failed gate on an existing PCB.
Sourcing and supply posture
As an active Texas Instruments part, the 74S32DC is available through authorized distribution channels; pricing and lead time are confirmed against the specific BOM quantity at the time of RFQ.
