3 Description
The TLC6C5912 is a monolithic, medium-voltage,
low-current power 12-bit shift register designed for
use in systems that require relatively moderate load
power, such as LEDs.
This device contains a 12-bit serial-in, parallel-out
shift register that feeds a 12-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.
This device contains a 12-bit serial-in, parallel-out
shift register that feeds a 12-bit D-type storage
register. Separate clocks are provided for both the
shift and storage registers.
Outputs are low-side, open-drain DMOS transistors
with output ratings of 40 V and 50-mA continuous
sink-current OR 200-mA PWM current with singlepulse
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 TLC6C5912 characterization is for operation over
the ambient temperature range of −40°C to 105°C.
