STANDBY MODE

To put the device in standby, just apply a logic

level on the standby MOS input. As ground is a vir-

tual level for the device, threshold voltage has

been refered to V

CC

CC

In standby mode, the output goes in high imped-

ance in 200ns. Be aware that all maximum rating

must still be followed in this mode. It leads to

swing limitation while using the device in signal

multiplexing configuration with followers, differen-

tial input voltage must not exceed

±5V limiting in-

put swing to 2.5Vpp.
