L293D is a four channel push-pull driver with a capability of 600mA output current and 1.2A peak output current. It features an enable facility, overtemperature protection, high noise immunity, etc. The driver is designed to drive inductive loads and switching power transistors and is suitable for switching applications at frequencies up to 5kHz.
The L293D and L293DD are monolithic integrated high‑voltage, high‑current four‑channel drivers designed to accept standard DTL or TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Each pair of channels can be enabled independently, and a separate logic supply allows operation at lower voltage. The device includes internal clamp diodes and is suitable for switching applications up to 5 kHz.
The datasheet lists absolute maximum ratings, thermal data, pin‑out diagrams, electrical characteristics for each channel, truth tables, and detailed mechanical dimensions for both the 16‑lead DIP (L293D) and 20‑lead SOIC (L293DD) packages.
| Supply Voltage (VSS) | 36 V |
|---|---|
| Peak Output Current (non‑repetitive) | 1.2 A per channel |
| Continuous Output Current | 600 mA per channel |
The device can tolerate up to 36 V on the supply pins.
Each channel can deliver a non‑repetitive peak current of 1.2 A.
