APPLICATIONS INFORMATION
considerably simpler. Decouple V+ and V– with 0.1F
ceramic capacitors.
Shutdown Control
The LT1332 has an ON/OFF pin that controls the device’s
mode of operation. With the ON/OFF pin high and the
device operated unloaded, the LT1332 draws 1mA of
supply current. With the ON/OFF pin low, the device
enters micropower shutdown mode in which the current
drawn from VCC drops to typically 40A. If the power
applied to V+ and V– remains on in shutdown, there will
be approximately 100A of leakage from each supply. If
these supplies drop to zero, leakage current also drops
to zero. In shutdown mode one receiver remains active
which may be useful for detecting start-up signals for
the transceiver.
Dimensions in inches (millimeters) unless otherwise noted.
