2006年6月12日 · darlington array circuits Hi, The only diference about a single darlington transistor and an array is that you have to respect de total power dissipation on that device, …

2007年7月27日 · darlington array wiki 245 is rather BUS-to-BUS buffer, it is like normal 3-state gates connected back-to-back .. Much better option would be to use 74(XX)05,06 or 07 which …

2008年1月23日 · darlington array ic hi all, i am trying to a speed controller circuit for an ac three phase motor, i found a circuit that includes transistors but if i do what is drawn on the circuit, …

2018年3月15日 · Hi, I wanted to Drive LEDs in Two Modes (Day/Night) and these LED has discrete status input hence I wanted to use IC something which has Enable Pin. Most of them …

2012年12月4日 · I need a photo darlington single or array with input current of 1 to 60 mA and o/p side current of 500 to 800 mA.

2010年8月5日 · I have a Darlignton Array (ULN2803A) which I am using with a Basic Stamp to trigger a solenoid. I connect 24V (from an Old Apple IBook Charger) as the power for the …

2009年4月14日 · 3.3v darlington array Attached the snapshot of ULN280x datasheet. I think I need to use ULN2801 (without base series resistor) as my GPIOs are 3.3V Vdd logic and can …

2024年11月24日 · Hi, I intend to implement a shift register and darlington array for controlling 15 relays sequentially. I am not sure though if I could control 15 relays with 2 SIPO's being driver …

2011年10月8日 · The darlington array has gnd connected to my 18v ground (not the same ground i use for all the other ICs), and the COM is hooked up to that same ground via a switch. The …

2011年3月13日 · Dear friends I need a "Darlington transistor array" but with opposite function of the ULN2803. I mean, it doesn't invert the input signal. thanks in advance.
