3 Description

The TLC6C598 device is a monolithic, mediumvoltage,

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. Separate clocks are provided for both the

shift and storage register. Outputs are low-side, opendrain

DMOS transistors with output ratings of 40 V

and 50 mA continuous sink-current OR 200-mA PWM

current with single-pulse duration less than 1 ms and

average current less than 50 mA capabilities when

VCC = 5 V. The device contains built-in thermal

shutdown protection and provides up to 2000 V of

ESD protection when tested using the human-body

model and the 200 V machine model.

The TLC6C598 characterization is for operation over

the operating ambient temperature range of ?40°C to

105°C.
