MAX4530 Maxim, MAX4530 Datasheet - Page 13

• Manufacturer Part Number: MAX4530
• Description: The MAX4530/MAX4531/MAX4532 are low-voltage, CMOS analog ICs configured as an 8-channel multiplexer (mux) (MAX4530), two 4-channel muxes (MAX4531), and three single-pole/double-throw switches (MAX4532)
• Manufacturer: Maxim

CHANNEL
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 TERMINAL ON EACH SWITCH.
CROSSTALK (MAX4531/MAX4532 IS MEASURED FROM ONE CHANNEL (A, B, C) TO ALL OTHER CHANNELS.
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
