TI TLC6C5912QDWRQ1

The TLC6C5912-Q1 is a monolithic, medium-voltage, low-current power 12-bit shift register designed for systems that require relatively moderate load power, such as LEDs. This device contains a 12-bit serial-in, parallel-out shift register that provides data to a 12-bit Class D storage register. Data transfer between the shift and storage registers occurs on the rising edges of the shift register clock (SRCK) and the register clock (RCK), respectively. When the shift register clear (CLR) is high, the storage register transfers data to the output buffer. A low level on CLR clears all registers in the device. Keeping the output enable (G̅) high holds all data in the output buffer low, and all drain outputs are off. Keeping G low makes the data from the storage register invisible to the output buffer. When the data in the output buffer is low, the output of the DMOS transistor is off. When the data is high, the DMOS transistor output has a current-sinking function. The serial output (SER OUT) shifts out of the device with the clock on the falling edge of SRCK, providing more hold time for cascaded applications. This can improve performance for applications where the clock signal may be skewed, devices that are not placed close to each other, or systems with high electromagnetic interference. This device has built-in thermal shutdown protection. The outputs are low-side open-drain DMOS transistors with a rated output voltage of 40V and a continuous current-sinking capability of 50mA at VCC = 5V. The current limit decreases as the junction temperature rises, providing additional device protection. The device also provides up to 2000V of ESD human-body model protection and 200V of ESD machine-model protection. The TLC6C5912-Q1 is rated for an operating ambient temperature range of -40°C to 125°C.
