DS18S20 Thermometer


The DS18S20 digital thermometer provides 9-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18S20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. In addition, the DS18S20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply

SG2803L-DESC datasheet

Description :


 Cross reference to 5962-86058012A, 5962-86058012, 86058012

 The SG2800 series integrates eight NPN Darlington pairs with internal suppression diodes to drive lamps, relays, and solenoids in many military, aerospace, and industrial applications that require severe environments. All units feature open collector outputs with greater than 50V breakdown voltages combined with 500mA current carrying capabilities. Five different input configurations provide optimized designs for interfacing with DTL, TTL, PMOS, or CMOS drive signals. These devices are designed to operate from -55°C to 125°C ambient temperature in a 18-pin dual in-line ceramic (J) package and 20-pin leadless chip carrier (LCC).

Key Features:
• Eight NPN Darlington pairs
• Collector currents to 600mA
• Output voltages from 50V to 95V
• Internal clamping diodes for inductive loads
• DTL, TTL, PMOS, or CMOS compatible inputs
• Hermetic ceramic package
