I/O

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.

VDD

Supply voltage. All VDD terminals 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.
