| L293C PUSH-PULL FOUR CHANNEL/DUAL H-BRIDGE DRIVER .600mAOUTPUTCURRENTCAPABI .1. .ENABLEFACI .OVERTEMPERATUREPROTECTI .LOGI .SEPARATEHI PRELIMINARY DATA LITY PER CHANNEL 2 A PEAK OUTPUTCURRENT (non repetitive) PER CHANNEL LITY ON CAL "0" INPUT VOLTAGE UP TO 1.5 V (high noise immunity) GH VOLTAGE POWER SUPPLY (up to 44 V) POWERDIP (16 + 2 + 2) ORDERING NUMBER : L293C PIN CONNECTION DESCRIPTION The L293C is a monolithic high voltage,high current integrated circuit four channel driver in a 20 pin DIP. It is designed to accept standard TTL or DTL input logic levels and drive inductive loads (such as relays, solenoids, DC and stepping motors) and switching power transistors. The device may easily be used as a dual H-bridge driver : separate chip enable and highvoltagepower supply pins are provided for each H-bridge. In addition, a separate power supply is provided for the logic section of the device. The L293C is assembled in a 20 lead plastic package which has 4 centerpins connectedtogetherand used for heatsinking.
