Description
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.
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.
