8-BIT SERIAL-INPUT,

CONSTANT-CURRENT

LATCHED LED DRIVER

TERMINAL DESCRIPTION

Terminal No.

Terminal Name

LOGIC GROUND

SERIAL DATA IN

CLOCK

Function

Reference terminal for control logic.

Serial-data input to the shift-register.

Clock input terminal for data shift on rising edge.

LATCH ENABLE

Data strobe input terminal; serial data is latched with high-level input.

HIGH/LOW

(CURRENT)

Logic low for 100% of programmed current level;

logic high for 50% of programmed current level.

7-14

POWER GROUND

OUT_0-7

Ground.

The eight current-sinking output terminals.

Ground.

POWER GROUND

OUTPUT ENABLE

When (active) low, the output drivers are enabled; when high, all output

drivers are turned OFF (blanked).

SERIAL OUT₂

SERIAL OUT₁

CMOS serial-data output (on clock falling edge).

CMOS serial-data output (on clock rising edge)

to the following shift-registers.

R_EXT

An external resistor at this terminal establishes the output current for all sink

drivers.

LOGIC SUPPLY

(V_DD) The logic supply voltage. Typically 5 V.
