TI TLC6C598CQDRQ1

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-in, parallel-out shift register that feeds 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 are capable of sinking current. The serial output (SER OUT) is clocked out of the device on the falling edge of SRCK to provide additional hold time required for cascaded applications. This improves performance in applications where the clock signal may be skewed, devices are not in close proximity to each other, or the system must withstand EMI. The device includes built-in thermal shutdown protection.

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

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