PIN FUNCTIONS
UU
U
SELECT (Pin 10): Channel Select. Use this pin to select
between RGB1 inputs and RGB2 inputs. Use this pin for
fast toggling. HIGH Selects RGB1.
V (Pins 11, 12): Negative Power Supply. Connect these
pins to – 5V and bypass with a good tantalum capacitor
(4.7
F). The pin may also require a 0.1F or 0.01F
depending on layout.
VOUTBLUE (Pin13): Blue Output. It is twice BLUE 1 or BLUE
2 depending on which channel is selected by Pin 10. VOUT
BLUE drives 50 or 75 double-terminated cables. Do not
add capacitance to this pin.
VOUT GREEN (Pin14): Green Output. It is twice GREEN 1 or
GREEN 2 depending on which channel is selected by Pin
10. VOUT GREEN drives 50 or 75 double-terminated
cables. Do not add capacitance to this pin.
VOUT RED (Pin 15): Red Output. It is twice RED 1 or RED 2
depending on which channel is selected by Pin 10. VOUT
RED drives 50 or 75 double-terminated cables. Do not
add capacitance to this pin.
V + (Pin 16): Positive Power Supply. Connect this pin to 5V
and bypass with a good tantalum capacitor (4.7
F). The
pin may also require a 0.1
F or 0.01F depending on
layout.
VOUT (Pin 6): It is twice VIN1 or VIN2 depending on which
channel is selected by Pin 5. VOUT drives 50 or 75
double-terminated cables. Do not add capacitance to this
pin.
ENABLE (Pin 7): Ground this pin for normal operation.
Take this pin to within 300mV of V+, or open to shut down
the part. This pin is also used for router applications. When
the part is disabled, the supply current is 0.3
A.
V + (Pin 8): Connect this pin to 5V and bypass with a good
tantalum capacitor (4.7
F). The pin may also require a
0.1
F or 0.01F depending on layout.
LT1675-1
VIN1 (Pin 1): The 1V video input signal to be switched is
applied to this pin. If 2V is applied to this pin, VOUT will clip.
The input must be terminated.
GND (Pin 2): Signal Ground. Connect to ground plane.
VIN2 (Pin 3): The 1V video input signal to be switched is
applied to this pin. If 2V is applied to this pin, VOUT will clip.
The input must be terminated.
V (Pin 4): Connect this pin to – 5V and bypass with good
tantalum capacitor (4.7
F). The pin may also require a
0.1
F or 0.01F depending on layout.
SELECT (Pin 5): Use this pin to select VIN1 or VIN2. Use this
pin for fast toggling. HIGH Selects VIN1.

RED 1 (Pin 1): Red 1 Input. The 1V video input signal to be
switched is applied to this pin. If 2V is applied to this pin,
VOUT RED will clip. The input must be terminated.
GREEN 1 (Pin 2): Green 1 Input. The 1V video input signal
to be switched is applied to this pin. If 2V is applied to this
pin, VOUT GREEN will clip. The input must be terminated.
BLUE 1 (Pin 3): Blue 1 Input. The 1V video input signal to
be switched is applied to this pin. If 2V is applied to this pin,
VOUT BLUE will clip. The input must be terminated.
GND (Pins 4, 5): Signal Ground. Connect to ground plane.
RED 2 (Pin 6): Red 2 Input. The 1V video input signal to be
switched is applied to this pin. If 2V is applied to this pin,
VOUT RED will clip. The input must be terminated.
GREEN 2 (Pin 7): Green 2 Input. The 1V video input signal
to be switched is applied to this pin. If 2V is applied to this
pin, VOUT GREEN will clip. The input must be terminated.
BLUE 2 (Pin 8): Blue 2 Input. The 1V video input signal to
be switched is applied to this pin. If 2V is applied to this pin,
VOUT BLUE will clip. The input must be terminated.
ENABLE (Pin 9): Chip Enable. Ground this pin for normal
operation. Take this pin to within 300mV of V+, or open to
shut down the part. This pin is also used for router
applications. When the part is disabled, the supply current
is 1
A.
