Data Input. Eight inputs are provided for the data, which pass through the

shift register unchanged. The TMC2111A consists of a single group of

eight bits with all data bits having equal delays.

Data Output. The outputs of the shift register are delayed relative to the

input signals. The amount of the delay is programmable (see Table 1).

Master Clock. All inputs and outputs are synchronous and operate from a

single master clock. All operations occur on the rising edge of the master

clock.

Length Select. The length select input is used to determine the register

after the clock edge after it is input to the device (see Timing Diagram).

Delay lengths are specified in Table 1.
