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,

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 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.

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.
