MAX4814E Maxim, MAX4814E Datasheet - Page 13

• Manufacturer Part Number: MAX4814E
• Description: The MAX4814E high-definition multimedia interface (HDMI) switch provides routing for low-frequency signals
• Manufacturer: Maxim

— = Denotes no connection.
1 = Denotes switch connection.
0 = Denotes switch B is high impedance.
X = Don’t care.
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings, since stresses beyond the listed ratings
can cause permanent damage to the device. Always
