MIC5800 Datasheet | Microchip Technology

MIC5800/1 4/8-Bit Parallel-Input Latched Drivers Features - 4.4 MHz Minimum Data Input Rate - High-Voltage, High-Current Sink Outputs - Output Transient Protection - CMOS, PMOS, NMOS, and TTL patible Inputs - Internal Pull-Down Resistors - Low-Power CMOS Latches Package Types General Description The MIC5800 and MIC5801 latched drivers are high-voltage, high-current integrated circuits prised of four or eight CMOS data latches, a bipolar Darlington transistor driver for each latch, and CMOS control circuitry for the mon CLEAR, STROBE, and OUTPUT ENABLE functions. The bipolar/MOS bination provides an extremely low-power 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 5 MHz. With a 12V supply, significantly higher speeds are obtained. The CMOS inputs are patible 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 500 m A 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 acplished by a reduction in duty cycle. Outputs may be connected in parallel for higher load current capability.
