V Clamp Diodes Inputs Compatible With Various Types of Logic Relay Driver Applications Higher-Voltage Versions of ULNA and ULNA, for Commercial Temperature Range description D OR N PACKAGE (TOP VIEW) B B B B B B B E 8 C C C C C C C COM The SN8 and SN are monolithic high-voltage, high-current Darlington transistor arrays. Each consists of seven npn Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of each Darlington pair is ma. The Darlington pairs may be paralleled for higher current capability. Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers. The SN8 has a -Ω series base resistor for each Darlington pair for operation directly with TTL or -V CMOS. The SN has a.-kω series base resistor to allow its operation directly with CMOS or PMOS that use supply voltages of to V. The required input current is below that of the SN8. logic symbol logic diagram B B B B B B B CLAMP COM C C C C C C C B B B B COM C C C C This symbol is in accordance with ANSI/IEEE Std-8 and IEC publication -.
