MC14569B
Programmable Divide-By-N
Dual 4-Bit Binary/BCD
Down Counter
The MC14569B is a programmable divide–by–N dual 4–bit binary
or BCD down counter constructed with MOS P–channel and
N–channel enhancement mode devices (complementary MOS) in a
monolithic structure.
This device has been designed for use with the MC14568B phase
comparator/counter in frequency synthesizers, phase–locked loops,
and other frequency division applications requiring low power
dissipation and/or high noise immunity.
• Speed–up Circuitry for Zero Detection
• Each 4–Bit Counter Can Divide Independently in BCD or Binary
Mode
• Can be Cascaded With MC14526B for
Frequency Synthesizer Applications
• All Outputs are Buffered
• Schmitt Triggered Clock Conditioning

1. Maximum Ratings are those values beyond which damage to the device
may occur.
2. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C
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
v v ^{high–impedance circuit. For proper operation, Vin and Vout should be constrained}
to the range V_SS (V_in or V_out) V_DD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either V_SS or V_DD). Unused outputs must be left open.
