DESCRIPTION
R/W
36
I _{Read/write input. This TTL-compatible control input is latched on the falling edge of CE (see Figure 1). When}
low, R/W writes data to the device. Data is internally latched on the rising edge of CE. When high, R/W reads
data from the device.
SYNC
68
I Composite sync control input. This TTL-compatible SYNC input is stored in the input latch on the rising edge
of LD. When low, SYNC turns off a 40 IRE current source on the IOG output (see Figure 3). This input does
not override any control data input (see Table 6). It should be brought low during the blanking interval only (see
Figure 3). When high, SYNC allows the device to perform in the standard manner.

† _{Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. This is a stress rating only, and}
functional operation of the device at these or any other conditions beyond those indicated in the recommended operating conditions section of
this specification is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values are with respect to GND.
