Description
The TMC2011A and TMC2111A are high-speed, byte-wide
shift registers with programmable delay lengths.
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.
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.
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.
The TMC2111A is a byte-wide shift register that can be pro-
grammed to lengths of 1 to 16 stages.
