4 / 4 page CD 44 SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE © 2002 TELEDYNE RELAYS CD\072002\Q1 NOTES: 1. Control input is compatible with CMOS or open collector TTL (with pull up resistor). 2. The rated input voltage is 5V for all tests unless otherwise specified. 3. Transient blocking voltage tests are performed per MIL-STD-704 (28 Vdc systems). 4. For bias voltages above 6V, a series resistor is required. Use the standard resistor value equal to or less than the value found from Figure 8. 5. To calculate the maximum ON resistance for a given junction temperature, find the normalized ON resistance factor (NR) from Figure 4. Calculate the new ON resistance as follows: (CD00CD, CD01CD) R (ON) = NR • RON @ 25°C (CD20CD, CD21CD) R (ON) = 0.2 • NR + 0.21 6. Overload testing to the requirements of MIL-PRF-28750 is constrained to the limits imposed by the short circuit protection characteristics as defined in this specification. System series inductance for “shorted-load” mode of operation should be 30 µH maximum. Maximum repetition rate into a shorted load should not exceed 10 Hz. 7. A status pull up resistor is required for proper operation of the status output. Determine the current (Iso) required by the status interface. Calculate the current (Is) through the status resistor such that the sink current through the status output is 2 mA. Select the status resistor such that it does not allow more than 2 mA to flow through the status output. R STATUS = V STATUS - 0.3V 2 mA - Iso 8. Inductive loads should be diode suppressed. Input transitions should be ≤ 1 ms duration and the input drive should be a bounceless contact type.
