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 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 micropro-
cessor 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 resis-
tors. The bipolar Darlington outputs are suitable for directly driving
many peripheral/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 simul-
taneous 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.
