TD62064,074P/AP/F/AF is a high-voltage, high-current Darlington driver from Toshiba. It consists of four NPN Darlington pairs. The chip has integrated clamping diodes for switching inductive loads, and all TD62074P/AP/F/AF units have uncommitted collectors and emitters for isolated Darlington applications.
This Toshiba datasheet covers the TD62064P, TD62064AP, TD62064F, TD62064AF, TD62074P, TD62074AP, TD62074F and TD62074AF 4-channel high-current Darlington sink drivers. The devices are high-voltage, high-current drivers made up of four NPN darlington pairs, with integral clamp diodes for switching inductive loads; the TD62074 units additionally have uncommitted collectors and emitters for isolated darlington applications. Toshiba notes that the substrate (SUB) must be connected to the most negative voltage for proper operation.
The document gives maximum ratings, recommended operating conditions and electrical characteristics, along with test circuits, characteristic curves (IOUT - VCE(sat), IIN - VIN, PD - Ta, IOUT - duty cycle), package outline drawings for DIP16-P-300-2.54A and HSOP16-P-300-1.00, and precautions for use. Listed applications include relay, hammer, lamp and stepping motor drivers.
