Table 5-1 Pin Functions
PIN I/O DESCRIPTION
NAME NO.
SRCLR 3 I Shift register clear, active-low. The storage register transfers data to the output buffer when SRCLR is high. Driving SRCLR low clears all the registers in the device.
DRAIN0 23 O Open-drain output
DRAIN1 24 O Open-drain output
DRAIN2 1 O Open-drain output
DRAIN3 2 O Open-drain output
DRAIN4 11 O Open-drain output
DRAIN5 12 O Open-drain output
DRAIN6 13 O Open-drain output
DRAIN7 14 O Open-drain output
G 4 I Output enable, active-low. Channel enable and disable input pin. Having G low enables all drain channels according to the output-latch register content. When high, all channels are off.
PGND 5, 6, 7, 8, 17, 18, 19, 20 — Power ground, the ground reference pin for the device. This pin must connect to the ground plane on the PCB.
LGND 16 — Signal ground, the ground reference pin for the device. This pin must connect to the ground plane on the PCB.
RCK 9 I Register clock. The data in each shift register stage transfers to the storage register at the rising edge of RCK.
SER IN 22 I Serial data input. Data on SER IN loads into the internal register on each rising edge of SRCK.
SER OUT 15 O Serial data output of the 8-bit serial shift register. The purpose of this pin is to cascade several devices on the serial bus.
SRCK 10 I Serial clock input. On each rising SRCK edge, data transfers from SER IN to the internal serial shift registers.
VCC 21 I Power supply pin for the device. TI recommends adding a 0.1-μF ceramic capacitor close to the pin.
