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 .

• 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

2. Maximum Ratings are those values beyond which damage to the device

may occur.

3. Temperature Derating:

Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C T o 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

and V

out

should be constrained

to the range V

v (Vin or V

out

) v VDD.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either V

or VDD). Unused outputs must be left open.

4. Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.

5. The formulas given are for the typical characteristics only at 25_C.

6. To calculate total supply current at loads other than 50 pF: I

T(CL

) = IT(50 pF) + (CL – 50) Vfk

where: I

is in µA (per package), CL in pF, V = (VDD – VSS) in volts, f in kHz is input frequency, and k = 0.0015.
