PIN
BLOCK DIAGRA
CS/LD (Pin 1): Serial Interface Chip Select/Load Input.
When CS/LD is low, SCK is enabled for shifting data on SDI
into the register. When CS/LD is taken high, SCK is dis-
abled and the specified command (see Table 1) is ex-
ecuted.
SCK (Pin 2): Serial Interface Clock Input. CMOS and TTL
compatible.
SDI (Pin 3): Serial Interface Data Input. Data is applied to
SDI for transfer to the device at the rising edge of SCK. The
