MC14534B
The MC14534B is composed of five BCD ripple counters that have their
respective outputs multiplexed using an internal scanner. Outputs of each
counter are selected by the scanner and appear on four (BCD) p ins.
Selection is indicated by a logic high on the appropriate digit select pin. Both
BCD and digit select outputs have three–state controls providing an
“open–circuit” when these controls are high and allowing multiplexing.
Cascading may be accomplished by using the carry–out pin. The counters
and scanner can be independently reset by applying a high to the counter
master reset (MR) and the scanner r eset (SR). The MC14534B was
specifically designed for application in real time or event counters where
continual updating and multiplexed displays are used.

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

#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.
