WebIC7447 is BCD to 7 segment decoder & display driver. It is available in 16 pin DIP package. Pin number 3 is display test (lamp test) function which is active low. When pin number 3 input is low, irrespective of other input pin signals, all the segment outputs a,b,c,d,e,f & g are low & all segments of the display will glow. WebJan 17, 2013 · Flip-Flops and Registers Integrated-Circuit J-K Flip-Flop (7476, 74LS76) The 7476 is a master—slave J-K and the 74LS76 is a negative edge-triggered J-K flip-flop. Both chips have the same pin configuration. Both chips have synchronous inputs of J, K and Cp. Both chips have asynchronous inputs.

For the 74ls74 dual D-type flip-flop to toggle, pin-1, pin-4 and pin-14 to Vcc, pin-7 to 0v, pin-6 connected directly to pin-2. A positive going pulse applied to pin-3 will cause pin-5 (Q) to change state every second pulse on pin-3 ... WebDec 27, 2024 · The above circuit diagram represents a 3-bit Johnson counter using a 7474 D flip-flop. You can easily extend this circuit up to 4-bit, 5-bit, etc. by adding flip-flops after the 3rd flip-flop. A single 7474 IC consists of 2 flip-flops. So you need two 7474 ICs for implementing the Johnson ring counter. Initially, all the flip-flops are cleared. solid wood impact doors
