... The LC7942YD chips are cascaded by connecting DIO64 on chip I to DIO1 on chip 2. For a 100 register, 037 to 064 on chip 2 are left open. 2. The LC7940YD (or LC7941YD) chips are cascaded by connecting CDO on chip I to CDI on chip 2, and CDO on chip 2 to CDI on chip 3. CDI on chip I is tied to GND, and CDO on chip 3 is not used. This confi ...

... SDI If this timing data is sent, data elements (m, 229), (m, 230), (m+1, 229), (m+1. 230)... will not appear in the output (O69 and O70 on chip 3). This is because the LC7940YD (or LC7941YD) converts serial/parallel data LOAD SDI m,1 m,2 In this case, (m, 231) is output on O71 on chip 3, and (m, 232) on O72 on chip 3. However, these outputs are not Specifi ...
