DESCRIPTION Designed to interface logic to a wide variety of high current, high voltageloads, these devices each contain four NPN darlington switches delivering up to 1.5 A with a specified minimum breakdown of 80 V and a sustaining voltage of 50 V. The ULN2065B, ULN2067B, ULN2069B and ULN2071B contain integral suppression diodes for inductive loads and have common emitters ; the ULN2075B and ULN2077B feature isolated darlington pinouts and are intended for applications such as emitter follower configurations. Inputs of the ULN2065B, ULN2069B and ULN2075B are compatible with popular 5 V logic families and the ULN2067B, ULN2071B and ULN2077B are compatible with 615 VCMOS and PMOS. The ULN2069B and ULN2071B include a predriver stage to provide extragain, reducing the load on control logic. PIN CONNECTIONS AND ORDER CODES

MOUNTING INSTRUCTIONS The Rth j-amb can be reduced by soldering the GND pins to a suitable copper area of the printed circuit board (Fig. 12) or to an external heatsink (Fig. 13). The diagram of figure 14 shows the maximum dissipable power Ptot and the Rth j-amb as a function of the side "" of two equal square copper areas having a thickness of 35 (1.4 mils). Figure 12 : Example of P.C. Board Area which is Used as Heatsink.
During soldering the pins temperature must not exceed 260 C and the soldering time must not be longer than 12 seconds. The external heatsink or printed circuit copper area must be connected to electrical ground.
