FND9368 / FND9368DC

FND9368 / FND9368DC is a high-speed 7-segment decoder/driver/latch integrated circuit (IC) primarily manufactured by Fairchild Semiconductor. It is designed to drive common cathode LED displays directly without the need for external current-limiting resistors.

Technical Specifications

According to the Fairchild Semiconductor datasheet, the 9368DC features:

• Function: Decodes 4-bit binary (BCD) input into a hexadecimal format (0–9, A–F).
• Output Type: Constant current source outputs, typically providing 20 mA at 1.7V per segment.
• Integrated Latches: Includes 4-bit storage latches that allow data to be strobed at standard TTL speeds (typically 30 ns pulse width).
• Package: The "DC" suffix indicates a 16-pin Ceramic Dual-In-Line Package (Ceramic DIP).
• Operating Voltage: Standard  Vcc of 5.0V (±5% range).
• Temperature Range: Commercial grade operating from 0°C to +70°C.
• Special Features: Automatic ripple blanking for suppressing leading and trailing zeros.
