Power Shutdown Operating Sequence

all logical ones will be shifted out followed by logical
zeroes till CS goes high. Then the D
OUT
line will go into its
high impedance state. The LTC 1293/4/6 will remain in the
shutdown mode till the next CS cycle. There is no warm-
up or wait period required after coming out of the power
shutdown cycle so a conversion can commence after CS
goes low (see Power Shutdown Operating Sequence). The
LTC1296 has a System Shutdown Output pin (SSO) which
will go low when power shutdown is activated. The pin will
stay low till next CS cycle.
Microprocessor Interfaces
The LTC1293/4/6 can interface directly (without external
hardware) to most popular microprocessors (MPU) syn-
chronous serial formats (see Table 1). If an MPU without
a dedicated serial port is used, then three of the MPU’s
parallel port lines can be programmed to form the serial
link to the LTC1293/4/6. Included here are one serial
interface example and one example showing a parallel
port programmed to form the serial interface.
