other limits are assured by correlation with other
production tests and/or product design and char-
acterization. All signals referenced to GND. dBm
levels are into 600 ohms. Typicals specified at
VCC = + 5 V, VSS = -5 V, TA = 25 °C.
TRANSMISSION CHARACTERISTICS
Unless otherwise noted, limits printed in BOLD
characters are guaranteedfor VCC = + 5 V ± 5 % ;
VSS =– 5V ± 5%, TA =-40°Cto85°C bycorrelation
with 100 % electrical testing at TA = 25 °C (-40°C
to 85°C for TS5070-Xand TS5071-X).
