產品概述
The L293NE is a quadruple high current half H driver in 16 pin DIP package. This driver is designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors as well as other high current/high voltage loads in positive supply applICations. All inputs are TTL compatible. Each output is a complete totem pole drive circuit with darlington transistor sink and pseudo darlington source. Drivers are enabLED in pairs with drivers 1 and 2 enabled by pin 1, 2 and drivers 3 and 4 enabled by pin 3, 4. When an enable input is high, the associated drivers are enabled and their outputs are active and in phase with their inputs. When an enable input is low, those drivers are disabled and their outputs are off and in high impedance state. With proper data inputs each pair of drivers forms a full-H (or bridge) reversible drive. External high speed output clamp diodes should be used for inductive transient suppression.
