SLS SL4015BD, SL4015BN Datasheet
SL4015B
Semiconductor
Dual 4-Stage Static Shift Register
High-Voltage Silicon-Gate CMOS
The SL4015B 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 accomplished by a high level on the reset line. Register
expansion to 8 stages using one SL 4015B package, or to more than 8
stages using additional SL4015B’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 nA 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

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, VIN and V
GND≤(VIN or V
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC).
Unused outputs must be left open.
