74F114

Philips Semiconductors Product specification Dual J-K negative edge-triggered flip-flop with common clock and reset 74F114 DESCRIPTION The 74F114, Dual Negative edge-triggered JK-Type Flip-Flop with common clock and reset inputs, features individual J, K, Clock (CP), Set (SD) and Reset (RD) inputs, true and complementary outputs. The SD and RD inputs, when Low, set or reset the outputs as shown in the Function Table regardless of the level at the other inputs. A High level on the clock (CP) input enables the J and K inputs and data will be accepted. The logic levels and data will be accepted. The logic levels at the J and K inputs may be allowed to change while the CP is High and flip-flop will perform according to the Function Table as long as minimum setup and hold times are observed. Output changes are initiated by the High-to-Low transition of the CP.

For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. 2. All typical values are at VCC = 5V, Tamb = 25°C. 3. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, IOS tests should be performed last. 4. Measure ICC with the clock input grounded and all outputs open, with the Q and Q outputs High in turn. 1996 Mar 14 3 Philips Semiconductors Product specification Dual J-K negative edge-triggered flip-flop with common clock and reset 74F114 AC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL PARAMETER TEST CONDITION VCC = +5.0V Tamb = +25°C CL = 50pF, RL = 500Ω MIN fMAX tPLH tPHL tPLH tPHL Maximum clock frequency Propagation delay CP to Qn or Qn Propagation delay SDn, RD to Qn or Qn Waveform 1 Waveform 1 Waveform 2,3 85 2.0 2.0 2.0 2.0 TYP 100 5.0 5.5 4.5 4.5 6.5 7.5 6.5 6.5 MAX VCC = +5.0V ± 10% Tamb = 0°C to +70°C CL = 50pF, RL = 500Ω MIN 80 2.0 2.0 2.0 2.0 7.5 8.5 7.5 7.5 MAX MHz ns ns UNIT AC SETUP REQUIREMENTS LIMITS SYMBOL PARAMETER TEST CONDITION VCC = +5.0V Tamb = +25°C CL = 50pF, RL = 500Ω MIN tS(H) tS(L) th(H) th(L) tW(H) tW(L) tW(L) tREC Setup time, High or Low Jn, Kn to CP Hold time, High or Low Jn, Kn to CP CP Pulse width High or Low SDn, RD Pulse width Low Recovery time SDn, RD to CP Waveform 1 Waveform 1 Waveform 1 Waveform 2,3 Waveform 2,3 4.0 3.5 0.0 0.0 4.5 4.5 4.5 4.5 TYP MAX VCC = +5.0V ± 10% Tamb = 0°C to +70°C CL = 50pF, RL = 500Ω MIN 5.0 4.0 0.0 0.0 5.0 5.0 5.0 5.0 MAX ns ns ns ns ns UNIT AC WAVEFORMS For all waveforms, VM = 1.5V.
