description
‘These quadruple Darlington switches are monolithic bipolar devices especially designed for high-current, ! high-voltage peripheral driver applications. The devices are designed to offer solutions to interface problems . involving electronic-discharge printers, bipolar and unipolar de motor drivers, telephone relays, LEDs, PIN diodes, end other high-current loads operating from negative power supplies. nas the The UDN2841 Is intended for current-sink applications with the load connected to ground and the device [EOS a! Switching the negative supply. The UDN2845 is a sink and source combination for use in bipolar switching Ms | applications where both ends of the load are floating, The UDN2841 and UDN2845 each feature inputs g 1 that are compatible with standard TTL and 5-volt CMOS signals. The p-n-p input transistor serves as a g level translator and the first n-p-n transistor ‘stage Is designed to provide sufficient current gain to drive & ' the output Darlington-connected pair. FA Driver channels 2 and 4 have uncommitted collectors and emitters while 1 and 3 have emitters internally < connected to the substrate, For proper operation, the substrate must be connected to the most-negative a . supply voltage. . g The UDN2841 and UDN2846 are characterized for ‘operation from — 20°C to 85°C. 2 | 4 | logic symbolt logic diagram t | a 2 | a . 1c t E36 1636 e . , ia eat oy ea | | fer 1838 OBL wee i mt “< 08 jee tt eae | | 0) 5 00) 39 a . ol Fs 10) 96 ey 2 va ve « cul ac a] ac : .
