3 Description

The TLC6C598-Q1 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.

This 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 registers on the rising edge of the shiftregister

clock (SRCK) and the register clock (RCK),

respectively. The storage register transfers data to

the output buffer when shift register clear (CLR) is

high. A low on CLR clears all registers in the device.

Holding the output enable (G) high, holds all data in

the output buffers low, and all drain outputs are off.

Holding G low makes data from the storage register

transparent to the output buffers. 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 serial output (SER

OUT) clocks out of the device on the falling edge of

SRCK to provide additional hold time for cascaded

applications. This provides improved performance for

applications where clock signals may be skewed,

devices are not located near one another, or the

system must tolerate electromagnetic interference.

The device contains built-in thermal shutdown

protection.

Outputs are low-side, open-drain DMOS transistors

with output ratings of 40 V and 50 mA continuous

sink-current capabilities when Vcc = 5 V. The current

limit decreases as the junction temperature increases

for additional device protection. The device also

provides up to 2000 V of ESD protection when tested

using the human-body model and 200 V when using

the machine model.

The TLC6C598-Q1 characterization is for for

operation over the operating ambient temperature

range of −40°C to 125°C.
