20 ns switching time (toggle)  
The GY4102A is a bipolar, monolithic SPDT video switch  
incorporating fast control logic. The analog signal path is  
characterised by low differential gain, low differential  
phase and low insertion loss, coupled with a ±0.1dB  
bandwidth of typically 100MHz into a 10pF load, using an  
external series resistor.  
make-before-break switching  
100 MHz at ±0.1dB, bandwidth (flattened)  
Pb-free and Green  
typically 0.04 dB insertion loss at 1 MHz  
typically 0.03 % differential gain at 3.58 MHz  
typically 0.01 degree differential phase at 3.58 MHz  
In demanding video applications the GY4102A features a  
typical switching glitch of less than 30mV over a 3ns  
period. The device offers toggle rates up to 50MHz. The  
control input is TTL and 5V CMOS compatible.

2. Electrical Characteristics  
2.1 Absolute Maximum Ratings  
Table 2-1 lists the absolute maximum ratings for the GY4102A. Conditions exceeding  
the limits listed may cause permanent damage to the device. This is a stress rating only  
and functional operation of the device at these or any other conditions above those  
listed in the operational sections of this specification is not implied. Exposure to absolute  
maximum rating conditions for extended periods may affect device reliability.
