channels in a high-impedance state. The internal charge pump is turned off when EN is
a logic-high.
16 16 QP
Active-Low Charge-Pump Enable Input. Drive QP low for normal operation. Drive QP
high to disable the charge pump with the switches still active at a reduced analog signal

Test Circuits/Timing Diagrams
MEASUREMENTS ARE STANDARDIZED AGAINST SHORT AT SOCKET TERMINALS.
OFF-ISOLATION IS MEASURED BETWEEN COM_ AND "OFF" USB_ TERMINAL ON EACH SWITCH.
ON-LOSS IS MEASURED BETWEEN COM_ AND "ON" USB_ TERMINAL ON EACH SWITCH.
CROSSTALK IS MEASURED FROM ONE USB_ CHANNEL TO ANOTHER USB_ CHANNEL.
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
