A6800/A6801  
DABiC-5 Latched Sink Drivers  
The A6800 and A6801 latched-input BiMOS ICs merge high-current,  
high-voltage outputs with CMOS logic. The CMOS input section con-  
sists 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,  
exible interface. These BiMOS power interface ICs greatly benet the  
simplication of computer or microprocessor I/O. The A6800 ICs each  
contain four latched drivers. A6801 ICs contain eight latched drivers.  
A6800SA  
A6800SL  
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 induc-  
tive 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 accom-  
plished by a reduction in duty cycle. Outputs may be paralleled for  
higher load current capability.  
A6801SA  
A6801SEP  
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.
