1 Features and Benefits 3.3 to 5 V logic supply range Up to 0 MHz data input rate High-voltage, high-current outputs Darlington current-sink outputs, with improved low-saturation voltages MOS, TTL compatible inputs Output transient protection Internal pull-down resistors Low-power MOS latches Packages A pin 7.6 mm DIP (A package) 8-pin PL (EP package) Approximate scale : A pin SOIN (L package) 4-pin SOIW (LW package) Description The A6800 and latched-input BiMOS Is merge high-current, high-voltage outputs with MOS logic. The MOS input section consists of 4 or 8 data (D type) latches with associated common LEAR,, and OUTPUT ENABLE circuitry. The power outputs are bipolar NPN Darlingtons. This merged technology provides versatile, flexible interface. These BiMOS power interface Is greatly benefit the simplification of computer or microprocessor I/O. The A6800 Is each contain four latched drivers. Is contain eight latched drivers. The MOS inputs are compatible with standard MOS 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 D motors, and so forth. All devices have open-collector outputs and integral diodes for inductive load transient suppression. The output transistors 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 drivers at maximum rated current can only be accomplished by a reduction in duty cycle. Outputs may be paralleled for higher load current capability. ontinued on the next page Functional Block Diagram SUPPLY OMMON V DD IN N OUT N LEAR GROUND OUTPUT ENABLE TYPIAL MOS LATH TYPIAL BIPOLAR DRIVE OMMON MOS ONTR OL 680.0H

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. 5
