TMC2011A/TMC2111A are high-performance, 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 pro-grammed to lengths of 1 to 16 stages. The TMC2011A and TMC2111A are fully synchronous, with all operations controlled by a single master clock. Input and output registers are positive-edge triggered D-type flip-flops. The length and mode controls are also registered. Both devices operate with a maximum clock rate of 40 MHz. Fabricated in a submicron CMOS process, the TMC2011A and TMC2111A are TTL-compatible, and are available in 24-pin CERDIP and Plastic DIP packages.
