MC14014B, MC14021B
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.
Features
• Synchronous Parallel Input/Serial Output (MC14014B)
• Asynchronous Parallel Input/Serial Output (MC14021B)
• Synchronous Serial Input/Serial Output
• Full Static Operation
• “Q” Outputs from Sixth, Seventh, and Eighth Stages
• Double Diode Input Protection
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Capable of Driving Two Low−power TTL Loads or One Low−power
Schottky TTL Load Over the Rated Temperature Range
• MC14014B Pin−for−Pin Replacement for CD4014B
• MC14021B Pin−for−Pin Replacement for CD4021B
• NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100
Qualified and PPAP Capable
• This Device is Pb−Free and is RoHS Compliant

Stresses exceeding those listed in the Maximum Ratings table may damage the
device. If any of these limits are exceeded, device functionality should not be
assumed, damage may occur and reliability may be affected.
1. Temperature Derating: “D/DW” Package: –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, V
in
and V
out
should be constrained
to the range V
SS
≤ (V

.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V
SS
or V
DD
). Unused outputs must be left open.
