Applications Information
1:2 Multiplexer for Low-Voltage
Graphics Controllers
The device provides the level shifting necessary to drive
two standard VGA ports using a single graphics controller.
Internal buffers drive the HSYNC_ and VSYNC_ signals to
VGA standard TTL levels. The DDC multiplexer provides
level shifting by limiting signal levels to less than 2.5V.
Power-Supply Decoupling
Bypass VCC to ground with a 1FF or larger ceramic
capacitor as close as possible to the device.
PCB Layout
High-speed switches such as the MAX14983E require
proper PCB layout for optimum performance. Ensure that
impedance-controlled PCB traces for high-speed signals
are matched in length and as short as possible. Connect
the exposed pad to a solid ground plane.
High-ESD Protection
Electrostatic discharge (ESD)-protection structures are
incorporated on all pins to protect against electrostatic
discharges up to Q2kV Human Body Model (HBM)
encountered during handling and assembly. All outputs
are further protected against ESD up to Q11kV (HBM)
without damage (see the Pin Description).
The ESD structures withstand high ESD both in normal
operation and when the device is powered down. After
an ESD event, the device continues to function without
latchup.
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents test
methodology and results.
Human Body Model
the current waveform it generates when discharged
into a low impedance. This model consists of a 100pF
capacitor charged to the ESD voltage of interest that is
then discharged into the device through a 1.5kI resistor.
