74LS283 4-Bit Binary Adder With Fast Carry IC (74283 IC) DIP-16 Package

The 74F541 except that the inputs and outputs are on opposite sides of the package (see Connection Diagrams). This pinout arrangement makes these devices especially useful as output ports for microprocessors, allowing ease of layout and greater PC board density

Features :-

• 3-STATE outputs drive bus lines
• Inputs and outputs opposite side of package, allowing easier interface to microprocessors

The 74F244 is an octal buffer that is ideal for driving bus lines of buffer memory address registers. The outputs are all capable of sinking 64mA and sourcing up to 15mA, producing very good capacitive drive characteristics. The device features two output enables, OEa and OEb, each controlling four of the 3-State outputs. The 74F244 is functionally equivalent to the 74F244. It has been designed to reduce effects of ground noise. Other advantages are noted in the features

Features :-

• Octal bus interface
• 3-State output buffer sink 64mA
• 15mA source current

• Reduced ground bounce (74F244B)
• Reduced ICC (74F244B)
• Reduced loading (74F244B IIL = 40μA)
• Split lead frame offers increased noise immunity (74F244B)
• Industrial temperature range available (-40°C to +85°C) for 74F244
• 74F244 available in SSOP Type II package

The 74F109 is a dual positive edge-triggered JK-type flip-flop featuring individual J, K, clock, set, and reset inputs; also true and complementary outputs. Set (SD) and reset (RD) are asynchronous active low inputs and operate independently of the clock (CP) input. The J and K are edge-triggered inputs which control the state changes of the flip-flops as described in the function table. Clock triggering occurs at a voltage level and is not directly related to the transition time of the positive-going pulse. The J and K inputs must be stable just one setup time prior to the low-to-high transition of the clock for predictable operation. The JK design allows operation as a D flip-flop by tying J and K inputs together. Although the clock input is level sensitive, the positive transition of the clock pulse between the 0.8V and 2.0V levels should be equal to or less than the clock to output delay time for reliable operation

74HC109 Dual J-K Positive-Edge-Triggered Flip-Flop IC – DIP-16 Package The 74HC109 is a dual positive edge triggered JK flip-flop featuring individual nJ and nK inputs. It has clock (nCP) inputs, set (nSD) and reset (nRD) inputs and complementary nQ and nQ outputs. The set and reset are asynchronous active LOW inputs and operate independently of the clock input. The nJ and nK inputs control the state changes of the flip-flops as described in the mode select function table. The nJ and nK inputs must be stable one set-up time prior to the LOW-to-HIGH clock transition for predictable operation. The JK design allows operation as a D-type flip-flop by connecting the nJ and nK inputs together. Inputs include clamp diodes. It enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
