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.
