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 500 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 SN75468 has a 2700-Ω series base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS. The SN75469 has a 10.5-kΩ series base resistor to allow its operation directly with CMOS or PMOS that use supply voltages of 6 to 15 V. The required input current is below that of the SN75468. logic symbol† logic diagram CLAMP 1B 2B 3B 4B 5B 6B 7B 9 1 16 2 15 3 14 4 13 5 12 6 11 7 10 9 COM 1B 1 16 2 15 3 14 4 13 5 12 6 11 7 10 COM 1C 1C 2C 2B 2C 3C 4C 5C 3B 6C 7C † This symbol is in accordance with ANSI/IEEE Std91-1984 and IEC publication 617-12. 4B 5B 6B 7B 3C 4C 5C 6C 7C Copyright 1995, Texas Instruments Incorporated PRODUCTION DATA information is current as of publication date.
