MOTOROLA CMOS LOGIC DATAMC14035B
144
The MC14035B 4–bit shift register is constructed with MOS P–channel
and N–channel enhancement mode devices in a single monolithic structure.
It consists of a 4–stage clocked serial–shift register with synchronous
parallel inputs and buffered parallel outputs. The Parallel/Serial (P/S) input
allows serial–right shifting of data or synchronous parallel loading via inputs
DP0 thru DP3. The True/Complement (T/C) input determines whether the
outputs display the Q or Q
outputs of the flip–flop stages. J–K logic forms the
serial input to the first stage. With the J and K inputs connected together they
operate as a serial “D” input.
This device may be effectively used for shift–right/shift–left registers,
parallel–to–serial/serial–to–parallel conversion, sequence generation, up/
down Johnson or ring counters, pseudo–random code generation, frequency and phase comparators, sample and hold registers, etc . . .

#Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.
**The formulas given are for the typical characteristics only at 25_C.
†To calculate total supply current at loads other than 50 pF:
IT(CL) = IT(50 pF) + (CL – 50) Vfk
where: IT is in µA (per package), CL in pF, V = (VDD – VSS) in volts, f in kHz is input frequency, and k = 0.001.
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
out
should be constrained to the range VSS ≤ (Vin or V
out
) ≤ 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.
