TS3V340
QUAD SPDT HIGHĆBANDWIDTH VIDEO SWITCH
WITH LOW AND FLAT ONĆSTATE RESISTANCE
SCDS172A - JULY 2004 − REVISED DECEMBER 2004
description/ordering information (continued)
This device is fully specified for partial-power-down applications using I_off. The I_off feature ensures that
damaging current will not backflow through the device when it is powered down. This switch maintains isolation
during power off.
To ensure the high-impedance state during power up or power down, EN should be tied to V_CC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
