The supply voltage range is 4.5V to 5.5V.
The /B2A suffix typically denotes a specific screening or packaging variant (e.g., military-grade or ceramic package). The AM26S12/B2A is in a hermetic 20-CLCC package with a -55°C to 125°C temperature range, while the base AM26S12 may be available in plastic packages with a narrower temperature range. Confirm the exact suffix definition from the manufacturer's ordering guide.
