Specifications of PRL-420TD

• Rohs Compliant: NA
• Lead Free Status / RoHS Status: na

SPECIFICATIONS
Unless otherwise specified, dynamic measurements are made with all outputs terminated into 50Ω.
Notes:
(1). The output rise and fall times are measured with both the Q and
increase in rise and fall times will result.
(2). f MAX is measured by connecting its inputs to the PRL450ND, ECL to TTL Logic Level Translator, and its outputs to the PRL-350ECL comparator. The input
threshold voltage of the PRL-350ECL is set to 2V. The outputs of the PRL-350ECL are divided by two using the PRL-255. The outputs of the PRL 255 are then
measured using the PRL-550NQ5X, four channel ECL Terminators, connected to a 50Ω input sampling 'scope.
