DESCRIPTION
I _{Read/write input. This TTL-compatible control input is latched on the falling edge of CE (see Figure 1). When low, writes}
data to the device. Data is internally latched on the rising edge of CE. When high, reads data from the device.
I Composite sync control. This TTL-compatible sync control 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, as shown in Figure 3. This input does not override any
control data input, as shown in Table 6. It should be brought low during the blanking interval only, as shown in Figure 3.
When high, SYNC allows the device to perform in the standard manner.
VDD
Supply voltage. All VDD pins must be connected together.

† _{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 terminal.
