Description:
The NTE2075, 5鈥揷hannel sink driver, consists of 10 NPN transistors connected to form high current
gain driver pairs.
Features:
D
Output Sustaining Voltage to 20V
D
High Output Sink Current to 320mA
D
PMOS Compatible Input with Strobe Control
D
Wide Operating Temperature (T
A
= 鈥?0擄 to +75擄C)
Application:
Relay and printer driver, LED or incandescent display digit driver, interfacing for standard MOS/BI POLAR
logics.
Function:
The NTE2075 uses a predriver stage. Each input has a diode and 20k鈩?resistor in series to have
a wide input voltage range from 鈥?5V to +20V. All inputs can be controlled simultaneously by a strobe
input at Pin1. The power supply of the predrivers is connected to Pin14. All emitters and the substrate
are connected together to Pin7. The outputs are capable of sinking 320mA and will withstand 20V
in the OFF state.
