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, 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. 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 flipflops. 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.

Pin Number Pin Name Power VDD GND Data Inputs DI7-0 12,11,10, 9,4,3,2,1 14,13,12, 10,5,4,3,2 Data Input. Eight inputs are provided for the data, which pass through the shift register unchanged. The eight inputs on the TMC2011A are divided into two groups of four bits to allow mixed delay operation. The lengths of these two groups are different when the Mode Control (MC) is HIGH (see Table 1). When MC is LOW both groups have 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). The outputs remain valid for a minimum of tHO nanoseconds after the leading edge of CLK. This allow the data to be latched into circuits with non-zero hold time requirements. 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 delay of the TMC2011A. This input is registered and affects the output tDO after the clock edge after it is input to the device (see Timing Diagram). Delay lengths are specified in Table 1. Mode Control. The Mode Control is used to select the special 4-bit wide split mode. When HIGH, the delay on DO7-4 is fixed at 18 stages, while DO3-0 have the delay specified by the length select. When MC is LOW, all eight bits have equal delays as specified by the length select. 7 18 8 21,22 Supply Voltage. The TMC2011A and operates from a single +5V supply.
