description
The SN751508 and SN751518 are monolithic
integrated circuits designed to drive the data lines
of a dc plasma panel display. The SN751518 pin
sequence is reversed from the SN751508 for
ease in printed-circuit-board layout.
Each device consists of two 16-bit shift registers,
32 latches, 32 OR gates, and 32 pnp open-
collector output AND gates. Typically, a 32-bit
data string is split into two 16-bit data strings
externally and then entered in parallel into the shift
registers on the high-to-low transition of the clock
signal. A high LATCH ENABLE transfers the data
from the shift registers to the inputs of 32 OR gates
through the latches. Data present in the latch
during the high-to-low transition of LATCH
ENABLE is stored. When STROBE is high, the
latch is masked and a high is placed on the data
input of the output AND gates. When STROBE is
low and SUSTAIN is high, data from the latches is
reflected at the outputs. When low, SUSTAIN
forces all outputs to their off state. Drivers can be
cascaded via the serial data outputs of the static
shift registers. These outputs are not affected by
LATCH ENABLE, STROBE, or SUSTAIN.
The SN751508 and the SN751518 are
characterized from 0°C to 70°C.
