MAX4885 Maxim, MAX4885 Datasheet - Page 4

• Manufacturer Part Number: MAX4885
• Description: The MAX4885 integrates high-bandwidth analog switches and level translating buffers to implement a complete 1:2 or 2:1 multiplexer for VGA signals
• Manufacturer: Maxim

Complete VGA 1:2 or 2:1 Multiplexer
TIMING CHARACTERISTICS
(V+ = +5.0V ±10%, V
+25°C, unless otherwise noted.) (Note 2)
Note 2: Timing parameters are guaranteed by design and correlation over the full operating temperature range.
