They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. These devices are programmable frequency dividers. The type shave two clock inputs, either one may be used for clock gating. (see the function table). The HC292/7292 can divide from 22 to 231, and the HC294/7294 can divide from 22 to 215. The types feature an active-low clear input to initialize the state of all flip-flops. To facilitate incoming inspection, test points are provided.

74F194 4-Bit Bidirectional Universal Shift Register IC (74194) DIP-16 Package

Read more
The functional characteristics of the 74F194 4-Bit Bidirectional Shift Register are indicated in the Logic Diagram and Function Table. The register is fully synchronous, with all operations taking place in less than 9ns (typical) for 74F, making the device especially useful for implementing very high speed CPUs, or for memory buffer registers. The 74F194 design has special logic features which increase the range of application. The synchronous operation of the device is determined by two Mode Select inputs, S0 and S1. As shown in the Mode Select-Function Table, data can be entered and shifted from left to right (shift right, Q0→Q1, etc.), or right to left (shift left,Q3→Q2, etc.), or parallel data  can be entered, loading all 4 bits of the register simultaneously. When both S0 and S1 are Low, existing data is retained in a hold (do nothing) mode. The first and last stages provide D-type Serial Data inputs (DSR, DSL) to allow multistage shift right or shift left data transfers without interfering with parallel load operation. Mode Select and data inputs on the74F194 are edge-triggered, responding only to the Low-to-High transition of the Clock (CP). Therefore, the only timing restriction is that the Mode Select and selected data inputs must be stable one setup time prior to the Low-to-High transition of the clock pulse. Signals on the Mode Select, Parallel Data (D0–D3) and Serial Data(DSR, DSL) can change when the clock is in either state, provide donly the recommended setup and hold times, with respect to the clock rising edge, are observed. The four Parallel Data inputs(D0–D3) are D-type inputs. Data appearing on (D0–D3) inputs whenS0 and S1 are High is transferred to the Q0–Q3 outputs respectively, following the next Low-to-High transition of the clock. When Low, the asynchronous Master Reset (MR) overrides all other input conditions and forces the Q outputs Low

Features :-

  • Shift right and shift left capability
  • Synchronous parallel and serial data transfer
  • Easily expanded for both serial and parallel operation
  • Asynchronous Master Reset
  • Hold (do nothing) mode

74HC109 Dual J-K Negative-Edge-Triggered Flip-Flops IC (74109) DIP-16 Package

Read more
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.

74F74 Dual D-Type Positive Edge-Triggered Flip-Flop IC (7474) DIP-14 Package

Read more
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
