4x1 Video Multiplexer
DATA SHEET
FEATURES
CIRCUIT DESCRIPTION
The GX4314 is a wideband video multiplexer implemented
in bipolar technology. This device is characterized by
excellent differential phase and gain in the enabled state,
veryhigh off-isolation in the disabled state and fully buffered
unilateralsignalpath. Make-before-break switchingassures
virtually glitch-free switching.
• low differential phase and gain
• wide bandwidth, 100 MHz at -1 dB (Flattened)
• small switching transient
•
4.5 to 11 volts supplies
For use in NxM routing matrices, the GX4314 features a
very high, nearly constant 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.
FUNCTIONAL BLOCK DIAGRAM
Logic inputs are TTL and 5V CMOS compatible, providing
address and chip select functions. The operation of the
devices is described in the Truth Table below.
