Texas Instruments’ 5400 and 7400 TTL quad 2-input NAND gate has been in continuous production since 1964 and is the progenitor of what is ... (E.G. an SR Latch) was due to NANDs’ simplicity at ...

When the converter input voltage rail (PVIN) ramps up, capacitive coupling through the parasitic gate-to-drain capacitance (C gd) could pull up on the gate of S1 and turn it on. A pulldown resistor on ...

The 'devastated' owner of an XL Bully-style mutt who broke the latch on a gate and escaped before mauling a father and his puppy has apologised for the terrifying attack.
