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.
