SLVS486 – SEPTEMBER 2003
DESCRIPTION
Data shift clock. Note that the internal connections are switched by MODE (pin #30). At
SCLK↑, the shift-registers selected by MODE shift the data.
Data input of serial I/F
Data output of serial I/F
Power supply voltage
Error output. XDOWN is open drain terminal. XDOWN gets L when LOD or TEF detected.
Data latch. Note that the internal connections are switched by MODE (pin #30). At XLAT↑, the
latches selected by MODE get new data.
