UHD-400

The UHD-400 is designed as one kind of power and relay drivers. Combining logic gates and high current switching transistors, it hermetically packaged, monolithic devices are used to drive incandescent or LED lamps, relays, solenoids, small DC motors and other peripheral power loads in military and aerospace applications.

UHD-400 has four features. (1)500mA output current sink capability. (2)Four logic types. (3)Pinning compatible with 54/74 logic series. (4)High voltage 40V. Those are all the main features.

Some absolute maximum ratings of UHD-400 have been concluded into several points as follow. (1)Its supply voltage would be 7V. (2)Its output voltage would be 5.5V. (3)Its output off-state voltage would be 40V. (4)Its output on-state sink current would be 500mA for one driver and 1A for total package. (5)Its suppression diode off-state voltage would be 40V. (6)Its suppression diode on-state current would be 500mA. (7)Its operating free-air temperature range would be from -55°C to 125°C. (8)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of UHD-400 are concluded as follow. (1)Its output reverse current would be max 100uA. (2)Its output voltage would be max 0.5V with output current of 150mA and would be max 0.7V with output current would be 250mA from -55°C to 25°C. (3)Its input voltage would be min 2.0V for high and would be max 0.8V for low. (4)Its input current would be max -800uA with conditions of driven input 0.4V and other input 4.5V. (5)Its supply current would be typ 4.0mA and max 7.5mA with conditions of driven input 5.0V and would be typ 17.5mA and max 26.5mA with conditions of driven input 0V. And so on.
