IW4015B
IW4015B is Dual 4-Bit Static Shift Register manufactured by IK Semiconductor.
TECHNICAL DATA
Dual 4-Stage Static Shift Register
The IW4015B consists of two identical, independent, 4-stage serialinput/parallel-output registers. Each register has independent CLOCK and RESET inputs as well as a single serial DATA input. “Q” outputs are available from each of the four stages on both registers. All register stages are D-type, master-slave flip-flops. The logic level present at the DATA input is transferred into the first register stage and shifted over one stage at each positive-going clock transition. Resetting of all stages is acplished by a high level on the reset line. Register expansion to 8 stages using one IW4015B package, or to more than 8 stages using additional IW4015B’s is possible.
- Operating Voltage Range: 3.0 to 18 V
- Maximum input current of 1 µA at 18 V over full package-temperature range; 100 n A at 18 V and 25°C
- Noise margin (over full package temperature range): 1.0 V min @ 5.0 V supply 2.0 V min @ 10.0 V supply 2.5 V min @ 15.0 V supply
