Programmable Timers And Oscillators FAQ

How is the selected counter stage connected to the output?

The A, B, C, and D inputs select which flip-flop stage connects to the Decode Out pin. An 8-Bypass input allows selection between stages 1-8 and 9-24.

What is the function of the MONO-IN pin?

The MONO-IN pin configures the internal monostable multivibrator. Connecting it to VSS disables the monostable circuit, while connecting a resistor to VDD enables it for pulse width control.

Can the device operate with very slow clock signals?

Yes, the device includes a clock conditioning circuit that permits operation with inputs having very long rise and fall times.
