Function

Description

26

Latch Enable

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.

27

Data In

Serial data input.

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

28

Output Enable

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.

29

N/C

No connect.

30

HV

High voltage outputs.

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

loads either to a GND, or to V
