Therefore, by forcing input B to a logic low, Q2 is always closed and Q6 is always opened, and you can use A as input 1 and C as input 2, with the gate working as a two-input CMOS NAND gate.

NAND Gates Enable Trigger Lockout For 555 Timers April 14, 2003 Applications of commercially available integrated timers, including the NE/SE555, are fairly limited when used in their monostable mode.

It's time to dig inside to understand how the internal CPU components are designed. We'll discuss transistors, logic gates, power and clock delivery, design synthesis, and verification.
