Feature Description (continued)
8.3.3 Output Voltage Clamps
Separate inputs, V_CL– and V_CL+, establish the minimum and maximum output voltages, respectively. The typical
error of the output voltage compared to the clamp voltage is only 25 mV. This feature can be used to avoid
saturating the inputs of a receiving device, thereby precluding long recovery times in the signal path.
8.3.4 Power-Down Mode
To minimize power consumption when idle, the THS7530-Q1 device has an active-low power-down control that
reduces the quiescent current from 40 mA to 350 µA. The turnon delay is only 820 ns.
When in power-down mode, the THS7530-Q1 device has a 80-dB forward isolation to allow other devices to
drive the same signal path with minimal interference from the idle THS7530-Q1 device.
8.4 Device Functional Modes
The THS7530-Q1 device has two functional modes: full-power mode and power-down mode. The power-down
mode reduces the quiescent current of the device to 350 µA from a typical value of 40 mA.
With a turnon time of only 820 ns and a turnoff time of 500 ns, the power-down mode can be used to greatly
reduce the average power consumption of the device without sacrificing system performance.
