Output drive is rated at 12 mA source and sink per channel, sufficient for driving a heavily loaded bus with multiple fan-out or long PCB traces. The 3-state control on each element lets you put the outputs into high-impedance when the bus is driven by another master, avoiding contention.
No thermal pad — dissipation is low enough for the plastic package to handle without extra copper.
Design engineers need full electrical characteristics and timing diagrams to validate fit in their circuit.
Sourcing buyers need to find authorized distributors quickly to place a purchase order.
Price directly impacts BOM cost and budget approval for procurement decisions.
When the exact part is unavailable or EOL, engineers and buyers need drop-in replacements to avoid redesign.
Stock availability determines lead time; critical for urgent production needs.
Maintenance techs replacing a failed unit need pinout to verify correct placement and avoid wiring errors.
