74LS368 3-State Hex Bus Drivers IC (74368) DIP-16 Package

The  74F113  offers  individual  J,  K,  Set and  Clock inputs. When the clock goes  HIGH, the inputs are enabled  and data may be entered. The logic level of the J and K inputs may be changed when the clock pulse is HIGH and the flip-flop  will  perform  according  to  the  Truth  Table  as  long  as minimum setup and hold times are observed. Input data is transferred  to  the  outputs  on  the  falling  edge  of  the  clock pulse.

Features :-

• Asynchronous input: LOW input to SD sets Q to HIGH level Set is independent of clock

The 74F182 is a high-speed carry lookahead generator. It is  generally  used  with  the  74F181  or  74F381  4-bit  arithmetic  logic  units  to  provide  high-speed  lookahead  over word lengths of more than four bits

Features :-

• Provides lookahead carries across a group of four ALUs
• Multi-level  lookahead  high-speed  arithmetic  operation over long word lengths

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

Features :-

Industrial temperature range available (–40°C to +85°C)

The F74 is a dual D-type flip-flop with Direct Clear and Set inputs  and  complementary  (Q,  Q)  outputs.  Information  at the input is transferred to the outputs on the positive edge of the clock pulse. Clock triggering occurs at a voltage level of the clock pulse and is not directly related to the transition time of the positive-going pulse. After the Clock Pulse input threshold  voltage  has  been  passed,  the  Data  input  is locked out and information present will not be transferred to the  outputs  until  the  next  rising  edge  of  the  Clock  Pulse input.

Features :-

• Asynchronous Inputs:
• LOW input to SD sets Q to HIGH level
• LOW input to CD sets Q to LOW level
• Clear and Set are independent of clock
• Simultaneous LOW on CD and SD makes both Q and Q HIGH
