The TMC2011A and TMC2111A are high-speed, byte-wide shift registers with programmable delay lengths. The TMC2011A can be programmed to any length between 3 and 18 stages. It offers a special split-word mode which allows for mixed delay lengths. The TMC2011A, constructed in low-power CMOS, is pin and function compatible with the bipolar TDC1011. The TMC2111A is a byte-wide shift register that can be programmed to lengths of 1 to 16 stages.
