Description

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, con-

structed 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 as well as a

28-lead Plastic Leadless Chip Carrier.
