Dual H-Bridge Driver: Both L293 and L293E are dual H-bridge drivers, meaning they can independently control the direction and speed of two DC motors or a single stepper motor.Bidirectional Control: Each H-bridge allows bidirectional control, enabling motors to move forward or backward.High Output Current: The L293 is capable of driving currents up to 1 A per channel, while the L293E can handle up to 2 A per channel.Wide Operating Voltage Range: They operate on a wide motor supply voltage range, typically from 4.5 V to 36 V.Logic Level Compatibility: They are compatible with TTL and CMOS logic levels.Enable Pins: Separate enable pins allow for independent control of each pair of drivers (a full bridge).Thermal Shutdown: They include thermal shutdown protection to prevent damage from overheating.Internal Clamp Diodes: Internal clamp diodes are included for inductive load protection.High Noise Immunity: They feature high noise immunity inputs.Separate Power Supplies: Separate supply inputs are provided for the logic and the motors, allowing the logic to run off a lower voltage to reduce dissipation.Switchmode Control (L293E): The L293E has external connection of sensing resistors, enabling switchmode current control.
