CS Low During Conversion

TLH5587 – 5

Note

DO and DI lines share the 8-bit IO shift register(see Functional Block Diagram) Since the MUX address bits are shifted in on SCLK rising edges while SCLK

falling edges shift out conversion data on DO the eighth falling edge of SCLK will shift out the MSB MUX address bit (A7) on DO Thus if addressing channels

CH8–CH10 a high DO will occur momentarily (one w2 clock period) until the 8-bit IO shift register is cleared by the internal EOC signal
