BiMOS II LATCHED DRIVERS
The UCN5800A/L and UCN5801A/EP/LW 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 com-
mon 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 UCN5800A and
UCN5800L each contain four latched drivers; the UCN5801A, UCN5801EP,
and UCN5801LW contain eight latched drivers.
The UCN5800A/L and UCN5801A/EP/LW supersede the original
BiMOS latched-input driver ICs (UCN4400A and UCN4801A). These
second-generation devices are capable of much higher data input rates and
will typically operate at better than 5 MHz with a 5 V logic supply. Circuit
operation at 12 V affords substantial improvement over the 5 MHz figure.
The CMOS inputs are compatible with standard CMOS and NMOS
circuits. TTL circuits may mandate the addition of input pull-up resistors.
The bipolar Darlington outputs are suitable for directly driving many periph-
eral/power loads: relays, lamps, solenoids, small dc motors, etc.
All devices have open-collector outputs and integral diodes for
inductive load transient suppression. The output transistors are
capable of sinking 500 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 accomplished
by a reduction in duty cycle. Outputs may be paralleled for higher load
current capability.
The UCN5800A is furnished in a standard 14-pin DIP; the UCN5800L
and UCN5801LW in surface-mountable SOICs; the UCN5801A in a 22-pin
DIP with 0.400" (10.16 mm) row centers; the UCN5801EP in a 28-lead
PLCC.

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 condition, regardless
of any other input conditions. When the OUTPUT ENABLE is low, the
outputs depend on the state of their respective latches.
