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 shift-
register 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.
