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.

MOTOROLA CMOS LOGIC DATA MC14569B 3 PIN DESCRIPTIONS INPUTS CONTROLS P0, P1, P2, P3 (Pins 3, 4, 5, 6) — Preset Inputs. Programmable inputs for the least significant counter. May be binary or BCD depending on the control input. Cascade Feedback (Pin 7) — This pin is normally set high. When low, loading of the preset inputs (P0 through P7) is inhibited, i.e., P0 through P7 are “don’t cares.” Refer to Table 1 for output characteristics. P4, P5, P6, P7 (Pins 11, 12, 13, 14) — Preset Inputs. Programmable inputs for the most significant counter. May be binary or BCD depending on the control input. Clock (Pin 9) — Preset data is decremented by one on each positive transition of this signal. OUTPUTS CTL1 (Pin 2) — This pin controls the counting mode of the least significant counter. When set high, counting mode is BCD. When set low, counting mode is binary. CTL2 (Pin 10) — This pin controls the counting mode of the most significant counter. When set high, counting mode is BCD. When set low, counting mode is binary. SUPPLY PINS Zero Detect (Pin 1) — This output is normally low and goes high for one clock cycle when the counter has decremented to zero. VSS (Pin 18) — Negative Supply Voltage. This pin is usually connected to ground. Q (Pin 15) — Output of the last stage of the most significant counter. This output will be inactive unless the preset input P7 has been set high. VDD (Pin 16) — Positive Supply Voltage. This pin is connected to a positive supply voltage ranging from 3.0 volts to 18.0 volts. OPERATING CHARACTERISTICS The MC14569B is a programmable divide–by–N dual 4–bit down counter. This counter may be programmed (i.e., preset) in BCD or binary code through inputs P0 to P7. For each counter, the counting sequence may be chosen independently by applying a high (for BCD count) or a low (for binary count) to the control inputs CTL1 and CTL2. The divide ratio N (N being the value programmed on the preset inputs P0 to P7) is automatically loaded into the counter as soon as the count 1 is detected. Therefore, a division ratio of one is not possible. After N clock cycles, one pulse appears on the Zero Detect output. (See Timing Diagram.) The Q output is the output of the last stage of the most significant counter (See Tables 1 through 5, Mode Controls.) When cascading the MC14569B to the MC14568B, MC14522B or the MC14526B, the Cascade Feedback input, Q, and Zero Detect outputs must be respectively connected to “0”, Clock, and Load of the following counter. If the MC14569B is used alone, Cascade Feedback must be connected to VDD. 18 CL = 50 pF f, FREQUENCY (MHz), TYPICAL 16 PIN ASSIGNMENT 14 12 VDD = 15 V 10 8.0 10 V 6.0 4.0 5.0 V 2.0 0 – 40 – 20 MC14569B 4 0 + 20 + 40 + 60 TA, AMBIENT TEMPERATURE (°C) + 80 ZERO DETECT CTL1 1 16 VDD 2 15 Q P0 3 14 P7 P1 4 13 P6 P2 5 12 P5 P3 CASCADE FEEDBACK VSS 6 11 P4 7 10 CTL2 8 9 CLOCK + 100 MOTOROLA CMOS LOGIC DATA Table 1.
