Description
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,
fl exible interface. These BiMOS power interface ICs greatly
benefi t the simplifi cation of computer or microproces-
sor 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, and so forth.
All devices have open-collector outputs and integral diodes
for inductive load transient suppression. The output transis-
tors are capable of sinking 600 mA and can withstand at
least 50 V in the off state. Because of limitations on package
power dissipation, the simultaneous operation of all driv-
ers at maximum rated current can only be accomplished
by a reduction in duty cycle. Outputs may be paralleled for
higher load current capability.
