GX434 Monolithic 4x1  
Video Multiplexer  
DATA SHEET  
CIRCUIT DESCRIPTION  
FEATURES  
The GX434 is a high performance low cost monolithic 4x1  
video multiplexer incorporating four bipolar switches with a  
common output, a 2 to 4 address decoder and fast chip select  
circuitry. The chip select input allows for multi-chip paralleled  
operation in routing matrix applications. The chip is selected  
by applying a logic 0 on the chip select input.  
• low differential gain: 0.03% typ. at 4.43 MHz  
• low differential phase: 0.012 deg. typ. at 4.43 MHz  
• low insertion loss: 0.05 dB max at 100 kHz  
• low disabled power consumption: 5.2 mW typ.  
• high off isolation: 110 dB at 10 MHz  
Unlike devices using MOS bilateral switching elements, these  
bipolarcircuitsrepresentfullybuffered,unilateraltransmission  
paths when selected. This results in extremely high output to  
input isolation. They also feature fast make-before-break  
switching action. These features eliminate such problems as  
switching 'glitches' and output-to-input signal feedthrough.  
• all hostile crosstalk @ 5 MHz, 97 dB typ.  
• bandwidth (-3dB) with 30 pF load, 100 MHz typ.  
• fast make-before-break switching: 200 ns typ.  
• TTL and 5 volt CMOS compatible logic inputs  
• low cost 14 pin DIP and16 pin SOIC packages  
• optimised performance for NTSC, PAL and SECAM  
applications  
The GX434 operates from ±7 to ± 13.2 volt DC supplies. They  
are specifically designed for video signal switching which  
requires extremely low differential phase and gain. Logic  
inputsareTTLand5voltCMOScompatibleprovidingaddress  
and chip select functions. When the chip is not selected, the  
output goes to a high impedance state.
