TI TLC6C598QPWRQ1

The TLC6C598-Q1 is a monolithic medium-voltage low-current 8-bit shift register designed for systems requiring moderately low load power, such as LEDs. The device contains an 8-bit serial-input parallel-output shift register that transfers data to an 8-bit D-type storage register. Data is transferred through the shift register and storage register on the rising edges of the shift register clock (SRCK) and register clock (RCK), respectively. When the shift register clear (CLR) is high, the storage register transfers data to the output buffer. A low CLR clears all registers in the device. Holding the output enable (G) high forces all data in the output buffer low and turns off all drain outputs. Holding G low passes data from the storage register transparently to the output buffer. When data in the output buffer is low, the DMOS transistor outputs are off. When data is high, the DMOS transistor outputs have the ability to sink current. The serial output (SER OUT) is clocked out of the device on the falling edge of SRCK to provide additional hold time for cascading applications. This improves performance in applications where clock signals may be skewed, devices are not in close proximity to each other, or the system must be tolerant of EMI. The device incorporates thermal shutdown protection.

The outputs are low-side open-drain DMOS transistors with a continuous sink current capability of 40 V and 50 mA at Vcc = 5 V. As junction temperature increases, the current limit decreases, providing greater device protection. The device also provides ESD protection of up to 2000 V (tested using the human body model) and 200 V (tested using the machine model).

The TLC6C598-Q1 is characterized for operation over an ambient temperature range of -40°C to 125°C.
