ULN2001

UNISONIC TECHNOLOGIES CO., LTD ULN2001 LINEAR INTEGRATED CIRCUIT 3CH DARLINGTON SINK DRIVER  DESCRIPTION The UTC ULN2001 is high-voltage, high-current darlington transistor arrays. Each consists of three NPN darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of a single darlington pair is 500mA. All units feature integral clamp diodes for switching inductive loads. Applications include relay, hammer, lamp and display (LED) drivers. The UTC ULN2001 has a 2.7kΩ series base resistor for each darlington pair for operation directly with TTL or 5V CMOS devices.  FEATURES * Output Current (Single Output): 500mA max * High Sustaining Voltage Output: 50V min * Inputs Compatible with Various Types of Logic * Output Clamp Diodes * Relay-Driver Applications ■ ORDERING INFORMATION Ordering Number Lead Free Halogen Free ULN2001L-D08-T ULN2001G-D08-T ULN2001L-S08-R ULN2001G-S08-R Package DIP-8 SOP-8 Packing Tube Tape Reel  MARKING DIP-8 SOP-8 www.unisonic.com.tw Copyright © 2023 Unisonic Technologies Co., Ltd 1 of 6 QW-R113-021.B ULN2001  PIN CONFIGURATION INEAR INTEGRATED CIRCUIT  PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 PIN NAME I1 I2 I3 GND COMMON O3 O2 O1 1 Channel Input Pin 2 Channel Input Pin 3 Channel Input Pin Ground Clamp Diode 3 Channel Output Pin 2 Channel Output Pin 1 Channel Output Pin  BLOCK DIAGRAM O1 O2 8 7 DESCRIPTION O3 COMMON 6 5 1 2 3 ...
