GX4314L Low Power, Wideband
4 x 1 Video Multiplexer
DATA SHEET
DESCRIPTION
FEATURES
The GX4314L is a low power, wideband video multiplexer
implementedinbipolartechnology.Thisdeviceischaracterized
by excellent differential gain and phase in the enabled
state, very high off-isolation in the disabled state and a
fully buffered, unilateral signal path.
• low power; 12 mA ON current at ±5 volts
• low differential gain and phase
• wide bandwidth; 100 MHz at -1 dB
• ±4.5 to ±11 volt power supplies
Make-before-break switching assures virtually glitch-free
switching. TheGX4314Lfeaturesaveryhigh, nearlyconstant
input impedance coupled with high output impedance in
the disabled state. This allows multiple devices to be
paralleled at the inputs and outputs without additional
circuitry.
• available in 14 pin PDIP as well as 14 and 16
pin SOIC packaging
• identical functions and pin outs to GX4314 with lower
power
Logic inputs are TTL and 5 V CMOS compatible, providing
address and chip select functions. The operation of the
device is described in the Truth Table below.
FUNCTIONAL BLOCK DIAGRAM
The GX4314L offers pin for pin compatibility with Gennum's
other 4x1 multipliers such as GX414, GX414A and GX434
with greatly improved bandwidth and slew rate. Since the
GX4314L is capable of operation at ±5 V supplies, system
power can be reduced.

Typically, the ON current is only 12 mA while the chip
disabled current drops to less than 260 µA. This feature
allows the use of many devices in high density situations
without excessive power dissipation.
