MC14006B
The MC14006B shift register is comprised of four separate shift register
sections sharing a common clock: two sections have four stages, and two
sections have five stages with an output tap on both the fourth and fifth
stages. This makes it possible to obtain a shift register of 4, 5, 8, 9, 10, 12,
13, 14, 16, 17, or 18 bits by appropriate selection of inputs and outputs. This
part is particularly useful in serial shift registers and time delay circuits.
• Output Transitions Occur on the Falling Edge of the Clock Pulse
• Fully Static Operation
• Can be Cascaded to Provide Longer Shift Register Lengths
• 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
• Pin–for–Pin Replacement for CD4006B

#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.
