MAX4617/MAX4618/MAX4619
High-Speed, Low-Voltage, CMOS Analog
Multiplexers/Switches
14
Maxim Integrated
NOTES: MEASUREMENTS ARE STANDARDIZED AGAINST SHORT AT SOCKET TERMINALS.
OFF ISOLATION IS MEASURED BETWEEN COM AND "OFF" NO TERMINAL ON EACH SWITCH.
ON LOSS IS MEASURED BETWEEN COM AND "ON" NO TERMINAL ON EACH SWITCH.
CROSSTALK (MAX4618/MAX4619) IS MEASURED FROM ONE CHANNEL (A, B, C) TO ALL OTHER CHANNELS.
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
