How to Read Data Sheets: Logic Timing (Part 2, Latches)

Who would have thought that a circuit comprising only two 2-input NAND gates could be so complicated (or, should we say, “interesting”)? Up to this point (click here to see my earlier columns), the ...

NAND Gates Enable Trigger Lockout For 555 Timers

Applications of commercially available integrated timers, including the NE/SE555, are fairly limited when used in their monostable mode. This is due to their inability to function with all types of ...

Gated Oscillator Starts Without Delay

3. The scope image shows the CMOS gated oscillator with no startup delay. The yellow line is the control signal input, the blue line is the capacitor voltage, and the violet line is the NAND gate ...
