Function

Description

31

LE

Latch enable input.

When LE is HIGH, shift register data is transferred into a data latch. When LE is

LOW, data is latched, and new data can be clocked into the shift register.

32

DATA IN

Serial data input.

Data needs to be present before each rising edge of the clock.

33

OE

Output enable input.

When OE is LOW, all HV outputs are forced into a LOW state, regardless of data

in each channel. When OE is HIGH, all HV outputs reflect data latched.

34

N/C

No connect.

35

HV

High voltage outputs.

High voltage push-pull outputs, which, depending on controlling low voltage data,

can drive loads either to GND, or to V
