1 800 AND 80 Data Sheet B CLEAR 2 UCN800L UCN800A V DD 3 OUTPUT ENABLE SUPPLY The UCN800A/L and UCN80A/EP/LW latched-input BiMOS ICs merge high-current, high-voltage outputs with CMOS logic. The CMOS input section consists of or 8 data ( D type) latches with associated common CLEAR,, 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 UCN800A and UCN800L each contain four latched drivers; the UCN80A, UCN80EP, and UCN80LW contain eight latched drivers. IN IN 2 IN 3 IN GROUND 3 6 LATCHES OUT OUT Note the UCN800A (DIP) and the UCN800L (SOIC) are electrically identical and share a common terminal number assignment. COMMON Dwg.

The UCN800A/L and UCN80A/EP/LW supersede the original BiMOS latched-input driver ICs (UCN00A and UCN80A). These second-generation devices are capable of much higher data input rates and will typically operate at better than MHz with a V logic supply. Circuit operation at 2 V affords substantial improvement over the 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 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 00 ma and will withstand at least 0 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 UCN800A is furnished in a standard -pin DIP; the UCN800L and UCN80LW in surface-mountable SOICs; the UCN80A in a 22-pin DIP with 0.00" (0.6 mm) row centers; the UCN80EP in a 28-lead PLCC.
