LC7942KD drivers
An example using 1/100 duty cycle is shown below.
(1) The LC7942KD chips are cascaded by connecting DIO64 on chip 1 to DIO1 on chip 2.
For a 100-bit shift register, O37 to O64 on chip 2 are left open.
(2) The LC7940KD (or LC7941KDR) chips are cascaded by connecting CDO on chip 1 to CDI on chip 2,
and CDO on chip 2 to CDI on chip 3. CDI on chip 1 is tied to GND, and CDO on chop 3 is not used.
This configulation allows the input of 240-bit serial data.
