SAA1064/N2,112

Overview

The SAA1064/N2,112 is a four-digit LED display driver manufactured by NXP Semiconductors. It operates on an I2C bus interface and supports supply voltages between 4.5 V and 15 V. The device features sixteen outputs with a maximum output current of 110 mA and an output voltage of 3.5 V. It dissipates up to 1 W of power and functions within a temperature range of -40°C to 85°C. Packaged in a 24-pin DIP (0.600"), it drives up to 32 LEDs for digital displays.

Feature Summary

• Integrates I2C bus interface for simplified serial data transmission and control
• Provides dedicated drive capability for four-digit LED displays
• Supports high output current for reliable segment illumination

Applications

• Digital readout panels requiring I2C connectivity
