PIN CONFIGURATION

DESCRIPTION

M54562P and M54562FP are eight-circuit output-sourcing

Darlington transistor arrays. The circuits are made of PNP

and NPN transistors. Both the semiconductor integrated cir-

cuits perform high-current driving with extremely low input-

current supply.

FEATURES

≥ 50V)

High-current driving (Io(max) = –500mA)

With output clamping diodes

Driving available with PMOS IC output of 6 ~ 16V or with TTL output

Wide operating temperature range (Ta = –20 to +75

°C)

Output current-sourcing type

APPLICATION

Drives of relays, printers, LEDs, fluorescent display tubes

and lamps, and interfaces between MOS-bipolar logic sys-

tems and relays, solenoids, or small motors

FUNCTION

The M54562P and M54562FP each have eight circuits,

which are made of input inverters and current-sourcing out-

puts. The outputs are made of PNP transistors and NPN

Darlington transistors. The PNP transistor base current is

constant. A spike-killer clamping diode is provided between

among the eight circuits.

The inputs have resistance of 8.5k

Ω, and voltage of up to

30V is applicable. Output current is 500mA maximum. Sup-

The M54562FP is enclosed in a molded small flat package,

enabling space-saving design.
