DESCRIPTION

This

STPIC6C595

is

a

monolithic,

medium-voltage, low current power 8-bit shift

register designed for use in systems that require

relatively moderate load power such as LEDs. The

device contains a built-in voltage clamp on the

outputs for inductive transient protection. Power

driver applications include relays, solenoids, and

other low-current or medium-voltage loads.

The device contains an 8-bit serial-in, parallel-out

shift register that feeds an 8-bit D-type storage

register. Data transfers through both the shift and

storage register clock (SRCK) and the register

clock (RCK), respectively. The device transfers

data out the serial output (SER OUT) port on the

rising edge of SRCK. The storage register

transfers data to the output buffer when shift

register clear (CLR) is high. When CLR is low, the

input shift register is cleared. When output enable

(G) is held high, all data in the output buffer is held

low and all drain output are off. When G is held

low, data from the storage register is transparent

to the output buffer. When data in the output

buffers is low, the DMOS transistor outputs are off.

When data is high, the DMOS transistor outputs

have sink-current capability. The SER OUT allows

for cascading of the data from the shift register to

additional devices.

Output are low-side, open-drain DMOS transistors

with output ratings of 33V and 100mA continuous

sink-current capability. Each output provides a

current

as

the

increases

for

additional

device

protection. The device also provides up to 1.5KV

of

ESD

protection

when

tested

using

the

human-body model and 200V machine model.

The STPIC6C595 is characterized for operation

over the operating case temperature range of

-40°C to 125°C.
