INTEGRATED CIRCUITS 74F378 Hex D flip-flop with enable Product specification IC15 Data Handbook 1989 Oct 05 Philips Semiconductors Product specification Hex D flip-flop with enable 74F378 FEATURES TYPE • 6-bit high-speed parallel register • Positive edge-triggered D-type inputs • Fully buffered common Clock and Enable inputs • Input clamp diodes limit high speed termination effects • Fully TTL and CMOS compatible TYPICAL fmax TYPICAL SUPPLY CURRENT (TOTAL) 100MHz 35mA 74F378 ORDERING INFORMATION DESCRIPTION The 74F378 has six edge-triggered D-type flip-flops with individual D inputs and Q outputs. The common buffered Clock (CP) input loads all flip-flops simultaneously when the Enable (E) input is Low. DESCRIPTION COMMERCIAL RANGE VCC = 5V ±10%, Tamb = 0°C to +70°C PKG DWG # 16–pin plastic DIP N74F378N SOT38-4 16–pin plastic SO N74F378D SOT109-1 The register is fully edge-triggered. The state of each D input, one setup time before the Low-to-High clock transition is transformed to the corresponding flop-flop’s Q output. The E input must be stable one setup time prior to the Low-to-High clock transition for predictable operation.

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. 1989 Oct 05 4 Philips Semiconductors Product specification Hex D flip-flop with enable 74F378 AC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL PARAMETER fMAX Maximum clock frequency tPLH tPHL Propagation delay CP to Qn Tamb = +25°C VCC = +5.0V CL = 50pF, RL = 500Ω TEST CONDITION MIN TYP Waveform 1 80 100 Waveform 1 3.0 3.5 5.5 6.0 Tamb = 0°C to +70°C VCC = +5.0V ± 10% CL = 50pF, RL = 500Ω MAX MIN 7.5 8.5 3.0 3.5 UNIT MAX 80 MHz 8.5 9.5 ns AC SETUP REQUIREMENTS LIMITS SYMBOL PARAMETER Tamb = +25°C VCC = +5.0V CL = 50pF, RL = 500Ω TEST CONDITION MIN TYP MAX Tamb = 0°C to +70°C VCC = +5.0V ± 10% CL= 50pF, RL = 500Ω MIN UNIT MAX ts (H) ts (L) Setup time, High or Low Dn to CP Waveform 2 4.0 4.0 4.0 4.0 ns th (H) th (L) Hold time, High or Low Dn to CP Waveform 2 0 0 0 0 ns ts (H) ts (L) Setup time, High or Low E to CP Waveform 2 4.0 10.0 4.0 10.0 ns th (H) th (L) Hold time, High or Low E to CP Waveform 2 0 0 0 0 ns tw (H) tw (L) CP Pulse width, High or Low Waveform 1 4.0 6.0 4.0 6.0 ns AC WAVEFORMS For all waveforms, VM = 1.5V.
