Each consists of seven npn Darlington pairs that feature high-voltage outputs with mon-cathode clamp diodes for switching inductive loads. The collector-current rating of each Darlington pair is 500 m A. 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 1 1B 2 2B 3 3B 4 4B 5 5B 6 6B 7 7B CLAMP 16 1C 15 2C 14 3C 13 4C 12 5C 11 6C 10 7C † This symbol is in accordance with ANSI/IEEE Std91-1984 and IEC publication 617-12. 1 1B 2 2B 3 3B 4 4B 5 5B 6 6B 7 7B 16 1C 15 2C 14 3C 13 4C 12 5C 11 6C 10 7C PRODUCTION DATA information is current as of publication date.
