MOTOROLA MC14557BCL

SEMICONDUCTOR TECHNICAL DATA
The MC14557B is a static clocked serial shift register whose length may
be programmed to be any number of bits between 1 and 64. The number of
bits selected is equal to the sum of the subscripts of the enabled Length
Control inputs (L1, L2, L4, L8, L16, and L32) plus one. Serial data may be
selected from the A or B data inputs with the A/B select input. This feature is
useful for recirculation purposes. A Clock Enable (CE) input is provided to
allow gating of the clock or negative edge clocking capability.
The device can be effectively used for variable digital delay lines or simply
to implement odd length shift registers.
• 1–64 Bit Programmable Length
• Q and Q Serial Buffered Outputs
• Asynchronous Master Reset
• All Inputs Buffered
• No Limit On Clock Rise and Fall Times
• 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

** 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 Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ 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.
