8-Bit Static Shift Register
The MC14014B and MC14021B 8−bit static shift registers are
constructed with MOS P−channel and N−channel enhancement mode
devices in a single monolithic structure. These shift registers find primary
use in parallel−to−serial data conversion, synchronous and asynchronous
parallel input, serial output data queueing; and other general purpose
register applications requiring low power and/or high noise immunity.

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.

Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C
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 Vout should be constrained
to the range VSS v (Vin or Vout) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either VSS or VDD). Unused outputs must be left open.
