The SN51DP datasheet is reliable for new designs. No errata found in Rev 2.3 or later.
Designed for low-jitter operation, making it suitable for sensitive analog and digital signal processing. Pin Configuration (Typical)
: Measure the voltage spike at the panel output terminal during the initial turn-on sequence. A rise followed by an immediate drop to zero indicates active IC protection. Verified Protection Bypass Routine
Supports a maximum operating temperature of 85°C .
