100325 Low Power Hex ECL-to-TTL Translator
General Description
The 100325 is a hex translator for converting F100K logic levels to TTL logic levels. Differential inputs allow each circuit to be used as an inverting, non-inverting or differential receiver. An internal reference voltage generator provides VBB for single-ended operation, or for use in Schmitt trigger applications. All inputs have 50kΩ pull-down resistors. When the inputs are either unconnected or at the same potential the outputs will go LOW. When used in single-ended operation the apparent input threshold of the true inputs is 20mV to 40mV higher (positive) than the threshold of the complementary inputs. The VEE and VTTL power may be applied in either order.

Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Note 2: ESD testing conforms to MIL-STD-883, Method 3015.

Note 3: The specified limits represent the “worst case” value for the parameter. Since these values normally occur at the temperature extremes, additional noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are chosen to guarantee operation under “worst case” conditions. Note 4: Test one output at a time.

The specifications apply to any outputs switching in the same direction either HIGH-to-LOW (tOSHL), or LOW-to-HIGH (tOSLH), or in opposite directions both HL and LH (tOST).
