A6800 and A6801

DABiC-5 Latched Sink Drivers

Features and Benefits

▪ 3.3 to 5Vlogic supply range

▪ Up to 10 MHz data input rate

▪ High-voltage, high-current outputs

▪ Darlington current-sink outputs, with improved low-saturation

voltages

▪ CMOS, TTL compatible inputs

▪ Output transient protection

▪ Internal pull-down resistors

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,

ﬂexible interface. These BiMOS power interface ICs greatly

beneﬁt the simpliﬁcation of computer or microproces-

sor I/O. The A6800 ICs each contain four latched drivers.

A6801 ICs contain eight latched drivers.

▪ Low-power CMOS latches

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.

Packages

(A package)

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.
