Description:

The TLC6C598-Q1 is a monolithic, medium-voltage,low-current power 8-bit shift register designed for usein systems that require relatively moderate loadpower, such as LEDs.This device contains an 8-bit serial-in, parallel-outshift register that feeds an 8-bit D-type storageregister. Data transfers through both the shift andstorage registers on the rising edge of the shiftregister clock (SRCK) and the register clock (RCK),respectively. The storage register transfers data tothe output buffer when shift register clear (CLR) ishigh. A low on CLR clears all registers in the device.Holding the output enable (G) high, holds all data inthe output buffers low, and all drain outputs are off.Holding G low makes data from the storage registertransparent to the output buffers. When data in theoutput buffers is low, the DMOS transistor outputs areoff. When data is high, the DMOS transistor outputshave sink-current capability. The serial output (SEROUT) clocks out of the device on the falling edge ofSRCK to provide additional hold time for cascadedapplications. This provides improved performance forapplications where clock signals may be skewed,devices are not located near one another, or thesystem must tolerate electromagnetic interference.The device contains built-in thermal shutdownprotection.Outputs are low-side, open-drain DMOS transistorswith output ratings of 40 V and 50 mA continuoussink-current capabilities when Vcc = 5 V. The currentlimit decreases as the junction temperature increasesfor additional device protection. The device alsoprovides up to 2000 V of ESD protection when testedusing the human-body model and 200 V when usingthe machine model.The TLC6C598-Q1 characterization is for foroperation over the operating ambient temperaturerange of −40°C to 125°C.
