This page is for the sourcing of items in the UK/EU for Pedja Rogics' NOS DAC pcb. Some of the components are still sourced from the US because I haven't been able to find a supply more locally yet. Mouser electronics has a fixed shipping cost of $12 upto 4lb 2-3 weeks delivery. As the recommended CMOS clock comes from them it makes sense to order some more items from them at the same time. Also some items a priced more competitively. === Semiconductors === ||#||designation||value||Recommended Part||Supplier||Code||Price||stirling|| ||1||IC1, IC2, IC4||LM317||STmicro LM317T||farnell uk||412144||.||£1.01|| ||1||IC1, IC2, IC4||LM317||STmicro LM317T||Mouser||511-LM317T||$0.65||£0.36|| ||2||IC3||7805||STmicro L7805CV||farnell uk||412764||.||£0.46|| ||2||IC3||7805||STmicro L7805CV||Mouser||511-L7805CV||$0.55||£0.31|| ||3||IC5||LM337||STmicro LM337SP||farnell uk||412211||.||£1.89|| ||3||IC5||LM337||STmicro LM337SP||Mouser||511-LM337SP||$1.35||£0.75|| ||4||IC6||7824||STmicro L7824CV||farnell uk||413598||.||£0.27|| ||4||IC6||7824||STmicro L7824CV||Mouser||511-L7824CV||$0.65||£0.36|| ||5||IC7||TL431||TI TL431CLP||farnell uk||411838||.||£0.31|| ||5||IC7||TL431||TI TL431CLP||Mouser||595-TL431CLP||$0.39||£0.22|| ||6||IC8||7818||STmicro L7818CV||farnell uk||413537||.||£0.51|| ||6||IC8||7818||STmicro L7818CV||Mouser||511-L7818CV||$0.65||£0.36|| ||7||IC9||7918||STmicro L7918CV||farnell uk||414025||.||£0.45|| ||7||IC9||7918||STmicro L7918CV||Mouser||511-L7818CV||$0.65||£0.36|| ||8||IC10, IC12||7812||STmicro L7812CV||farnell uk||413203||.||£0.44|| ||8||IC10, IC12||7812||STmicro L7812CV||Mouser||511-L7812CV||$0.55||£0.31|| ||9||IC11, IC13||7912||STmicro L7912CV||farnell uk||413859||.||£0.45|| ||9||IC11, IC13||7912||STmicro L7912CV||Mouser||511-L7912CV||$0.65||£0.36|| ||10||IC101||CS8412-CP||.||.||.||.||.|| ||10a||IC101||CS8414-CS||.||.||.||.||.|| ||10b||IC101||SOIC Dip Adapter||.||.||.||.||.|| ||11||IC102||TDA1541A||.||.||.||.||.|| ||12||IC103, IC104||AD844AN||.||farnell uk||399000||.||£6.18|| ||13||T1||BC557||BC557||farnell uk||3164469||.||.|| ||14||J1, J2||2SK170BL||2sk170||grandata uk||2SK170||.||£0.50|| ||15||D1 -

In other words, pins 1, 4, 10 and 13 must be additionally connected to +5V. I can say that the LS (by ST) and F (by Fairchild) flip-flops worked with these pins left unconnected, but VHC, HC and AC (all by Fairchild) needed this external pull up. F series is open and defined but is not as full and clean as VHC. |
