●
3V micro computer compatible input
●
“L” active level input
●
With input diode
●
With clamping diodes
●
Wide operating temperature range (Ta = –40 to +85°C)
APPLICATION
Output for 3 voltage microcomputer series and interface with
high voltage system. Relay and small printer driver, LED, or
incandescent display digit driver.
FUNCTION
The M63836FP/KP is transistor-array of high active level
eight units type which can do direct drive of 3 voltage microcomputer series. A resistor of 3.5kΩ is connected between
the input and the base of PNP transistors. A clamp diode for
inductive load transient suppression is connected for the
output pin (collector) and COM pin. The input diode is intended to prevent the flow of current from the input to the
Vcc. without this diode, the current flows from “H” input to the
Vcc and the “L” input circuit is activated, in such a case
where one of the inputs of the 8 circuit is “H” and the other
are “L” to save power consumption. The diode is inserted to
prevent such mis-operation. The outputs are capable of driving 500mA and are rated for operation with output voltage up
to 50V.
