Product details

What the ratings mean for your BOM

The operating temperature range is -55°C to 125°C. The hermetic 20-CDIP package seals the silicon against moisture.

Lifecycle and sourcing reality

The SN54S244/BRA is listed with an Active lifecycle status, meaning Texas Instruments continues to manufacture it. There is no end-of-life notice or last-time-buy window. For long-life military and aerospace programs that cannot requalify a substitute, this is the part to freeze into the BOM. The part is RoHS non-compliant, which is expected for a hermetic ceramic package — lead-bearing solder finishes are standard for high-reliability applications and are often exempt from RoHS restrictions under military/ aerospace exemptions. Sourcing is through independent and authorized defense-channel distributors; availability and current pricing are confirmed at quote time against an RFQ.

Frequently asked questions

Where can I buy SN54S244/BRA available via RFQ confirmation?

The SN54S244/BRA is sourced and quoted to order against an RFQ through independent and authorized defense-channel distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and delivery commitment.

Is SN54S244/BRA equivalent to SN74S244?

Yes, the SN54S244/BRA is functionally and pin-for-pin equivalent to the commercial SN74S244. The key difference is the military temperature range (-55°C to 125°C) and the hermetic 20-CDIP package versus the commercial plastic DIP. It is a direct replacement when the application requires wider temperature tolerance or high-reliability qualification.

What is the pinout of SN54S244/BRA?

The SN54S244/BRA uses the standard 20-pin DIP pinout for the 54S244/74S244 family. Pin 1 is the output-enable bar for the first 4-bit section, pins 2-5 are the data inputs (1A1-1A4), pins 6-9 are the 3-state outputs (1Y1-1Y4), pin 10 is GND, pin 11 is the output-enable bar for the second section, pins 12-15 are the data inputs (2A1-2A4), pins 16-19 are the outputs (2Y1-2Y4), and pin 20 is VCC. The datasheet provides the full logic diagram and switching characteristics.

What is the price of SN54S244/BRA?

Pricing for the SN54S244/BRA is confirmed at quote time against an RFQ, as it varies with quantity, delivery schedule, and channel. Submit an RFQ for a current price quote tailored to your order volume.

What is the lead time for SN54S244/BRA?

Lead time for the SN54S244/BRA is confirmed at quote time against an RFQ. As an Active military-grade part, typical lead times depend on factory backlog and distributor inventory; a firm delivery commitment is provided with the quote.
