A6800 and A6801 DABiC-5 Latched Sink Drivers Features and Benefits Description ▪ 3.3 to 5 V logic 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 ▪ Low-power CMOS latches 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 microprocessor I/O. The A6800 ICs each contain four latched drivers. A6801 ICs contain eight latched drivers. Packages A6800 14-pin SOICN (L package) A6800 14-pin 7.62 mm DIP (A package) A6801 24-pin SOICW (LW package) A6801 28-pin PLCC (EP package) 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 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.

NOTE: Information present at an input is transferred to its latch when the STROBE is high. A high CLEAR input will set all latches to the output off condition regardless of the data or STROBE input levels. 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.
