The A6800 and A6801 latched-input BiMOS ICs merge high-current, high-voltage outputs with CMOS logic. The CMOS input section consists of 4 or 8 data (`D' type) latches with associated common CLEAR, STROBE, and OUTPUT ENABLE circuitry. The power outputs are bipolar NPN Darlingtons. This merged technology provides versatile, flexible interface. These BiMOS power interface ICs greatly benefit the simplification of computer or microprocessor I/O. The A6800 ICs each contain four latched drivers. A6801 ICs contain eight latched drivers. The CMOS inputs are compatible with standard CMOS circuits. TTL circuits may mandate the addition of input pull-up resistors. The bipolar Darlington outputs are suitable for directly driving many peripheral/ power loads: relays, lamps, solenoids, small dc motors, etc. All devices have open-collector outputs and integral diodes for inductive load transient suppression. The output transistors are capable of sinking 600 mA and will withstand at least 50 V in the OFF state. Because of limitations on package power dissipation, the simultaneous operation of all drivers at maximum rated current can only be accomplished by a reduction in duty cycle. Outputs may be paralleled for higher load current capability. The A6800SA is furnished in a standard 14-pin DIP; the A6800SL and A6801SLW in surface-mountable SOICs; the A6801SA in a 22-pin DIP with 0.400" (10.16 mm) row centers; the A6801SEP in a 28-lead PLCC. These devices are lead (Pb) free, with 100% matte tin plated leadframes.

NOTE: Information present at an input is transferred to its latch when the STROBE is high. A high CLEAR input will set all latches to the output off condition regardless of the data or STROBE input levels. A high OUTPUT ENABLE will set all outputs to the off contdition, regardless of any other input conditions. When the OUTPUT ENABLE is low, the outputs depend on the state of their respective latches. www.allegromicro.com 115 Northeast Cutoff, Box 15036 Worcester, Massachusetts 01615-0036 (508) 853-5000 4 Datasheet 26180.110 A6800/A6801 DABiC-5 Latched Sink Drivers A6800SL A6801SA 1 14 A6800SA CLEAR 1 22 OUTPUT ENABLE STROBE 2 VDD 21 SUPPLY 14 OUTPUT ENABLE IN 1 3 20 OUT 1 STROBE 2 VDD 13 SUPPLY IN 2 4 19 OUT 2 IN 1 3 12 OUT 1 IN 3 5 18 OUT 3 IN 2 4 11 OUT 2 IN 4 6 17 OUT 4 IN 3 5 10 OUT 3 IN 5 7 16 OUT 5 IN 4 6 9 OUT 4 IN 6 8 15 OUT 6 GROUND 7 8 COMMON IN 7 9 14 OUT 7 IN 8 10 13 OUT 8 GROUND 11 12 COMMON Dwg.
