MIC5800/5801 Micrel MIC5800/5801 4/8-Bit Parallel-Input Latched Drivers General Description Features The MIC5800/5801 latched drivers are high-voltage, highcurrent integrated circuits comprised of four or eight CMOS data latches, a bipolar Darlington transistor driver for each latch, and CMOS control circuitry for the common CLEAR, STROBE, and OUTPUT ENABLE functions. The bipolar/MOS combination provides an extremely lowpower latch with maximum interface flexibility. MIC5800 contains four latched drivers; MIC5801 contains eight latched drivers. Data input rates are greatly improved in these devices. With a 5V supply, they will typically operate at better than 5MHz. With a 12V supply, significantly higher speeds are obtained.The CMOS inputs are compatible with standard CMOS, PMOS, and NMOS circuits. TTL or DTL circuits may require the use of appropriate pull-up resistors. The bipolar outputs are suitable for use with relays, solenoids, stepping motors, LED or incandescent displays, and other high-power loads.Both units have open-collector outputs and integral diodes for inductive load transient suppression. The output transistors are capable of sinking 500mA and will sustain at least 50V 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. • • • • • • 4.4MHz Minimum Data Input Rate High-Voltage, Current Sink Outputs Output Transient Protection CMOS, PMOS, NMOS, and TTL Compatible Inputs Internal Pull-Down Resistors Low-Power CMOS Latches Ordering Information Part Number MIC5800BN MIC5800BM MIC5801BN 5962-8764001WA1 MIC5801BV MIC5801BWM 1 Temperature Range Package – 40°C to + 85°C – 40°C to + 85°C – 40°C to +85°C – 55°C to +125°C – 40°C to + 85°C – 40°C to +85°C 14–Pin Plastic DIP 14–Pin SOIC 22–Pin Plastic DIP 22–Pin CERDIP 28–Pin PLCC 24–Pin SOIC Standard Military Drawing number for MIC5801AJBQ 7 Functional Diagram VDD INn COMMON OUTn STROBE GND CLEAR OUTPUT ENABLE October 1998 COMMON MOS CONTROL TYPICAL MOS LATCH 7-11 TYPICAL BIPOLAR DRIVER MIC5800/5801 Micrel Typical Input Absolute Maximum Ratings: (Notes 1–6) at +25°C Free-Air Temperature V DD IN Output Voltage, VCE Supply Voltage, VDD Input Voltage Range, VIN Continuous Collector Current, IC Package Power Dissipation: MIC5800 Plastic DIP (Note 1) MIC5801 Plastic DIP (Note 2) MIC5800 SOIC (Note 3) MIC5801 PLCC (Note 4) MIC5801 CERDIP (Note 5) Operating Temperature Range, TA Storage Temperature Range, TS Note 1: Note 2: Note 3: Note 4: Note 5: Note 6: 50V 15V –0.3V to VDD + 0.3V 500mA 2.1W 2.5W 1.0W 2.25W 3.1W –40°C to +85°C –65°C to +125°C Derate at 16.7 mW/°C above TA = +25°C Derate at 20 mW/°C above TA = +25°C Derate at 8.5 mW/°C above TA = +25°C Derate at 18.2 mW/°C above TA = +25°C Derate at 25 mW/°C above TA = +25°C Micrel CMOS devices have input-static protection but are susceptible to damage when exposed to extremely high static electrical charges.

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.
