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,
very high off-isolation in the disabled state and fully buffered
unilateral signal path. Make-before-break switching assures
virtually glitch-free switching.
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.
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.
The wideband GX4314 is pin for pin compatible with the
high performance GX414, extending the flat frequency
response characteristics from 50 to 100 MHz.
APPLICATIONS
• HDTV
• Very high quality video switching
• Very high density video switching
• Computer graphics
• PCM / data routing
