Asynchronous counter constructed from JK flip flops. An asynchronous (ripple) counter is a "chain" of toggle (T) flip-flops in which the least-significant flip-flop (bit 0) is clocked by an external signal (the counter input clock), and all other flip-flops are clocked by the output of the nearest, less significant flip-flop (e.g., bit 0 clocks ...
J-K master-slave flip-flop 14 SN74104: 74x105 1 J-K master-slave flip-flop, J2 and K2 inverted 14 SN74105: 74x106 2 dual J-K negative-edge-triggered flip-flop, preset and clear 16 SN74H106: 74x107 2 dual J-K flip-flop, clear 14 SN74LS107A: 74x108 2 dual J-K negative-edge-triggered flip-flop, preset, common clear and common clock 14 SN74H108 ...
The JK flip-flop, augments the behavior of the SR flip-flop (J: Set, K: Reset) by interpreting the J = K = 1 condition as a "flip" or toggle command. Specifically, the combination J = 1, K = 0 is a command to set the flip-flop; the combination J = 0, K = 1 is a command to reset the flip-flop; and the combination J = K = 1 is a command to toggle ...
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
Flip-flop excitation tables [ edit ] In order to complete the excitation table of a flip-flop , one needs to draw the Q(t) and Q(t + 1) for all possible cases (e.g., 00, 01, 10, and 11), and then make the value of flip-flop such that on giving this value, one shall receive the input as Q(t + 1) as desired.
40175 – Quad D-type flip-flop. Each flip-flop has independent data, Q, /Q. All share clock and reset. Counters. 4017 – Decade counter with 10-output decoder. 4026 – Decade counter with 7-segment digit decoded output. 40110 – Up/down decade counter with 7-segment display decoder with 25 mA output drivers. 40192 – Up/down decade counter ...
The JK flip-flop augments the behavior of the SR flip-flop (J=Set, K=Reset) by interpreting the J = K = 1 condition as a "flip" or toggle command. This is an important distinction as it would confuse me to see S = R = 1 in the introduction sentence and then to read the Characteristic table, which has J = K = 1 for the flip.
A ring counter is a type of counter composed of flip-flops connected into a shift register, with the output of the last flip-flop fed to the input of the first, making a "circular" or "ring" structure. There are two types of ring counters:
