| INTEGRATED CIRCUITS 74F378 Hex D flip-flop with enable Product specification IC15 Data Handbook 1989 Oct 05 Philips Semiconductors Philips Semiconductors Product specification Hex D flip-flop with enable 74F378 FEATURES * 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 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. 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 = 25C. 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 TEST CONDITION Waveform 1 Waveform 1 Tamb = +25C VCC = +5.0V CL = 50pF, RL = 500 MIN fMAX tPLH tPHL Maximum clock frequency Propagation delay CP to Qn 80 3.0 3.5 TYP 100 5.5 6.0 7.5 8.5 MAX Tamb = 0C to +70C VCC = +5.0V 10% CL = 50pF, RL = 500 MIN 80 3.0 3.5 8.5 9.5 MAX MHz ns UNIT AC SETUP REQUIREMENTS LIMITS SYMBOL PARAMETER TEST CONDITION Tamb = +25C VCC = +5.0V CL = 50pF, RL = 500 MIN ts (H) ts (L) th (H) th (L) ts (H) ts (L) th (H) th (L) tw (H) tw (L) Setup time, High or Low Dn to CP Hold time, High or Low Dn to CP Setup time, High or Low E to CP Hold time, High or Low E to CP CP Pulse width, High or Low Waveform 2 Waveform 2 Waveform 2 Waveform 2 Waveform 1 4.0 4.0 0 0 4.0 10.0 0 0 4.0 6.0 TYP MAX Tamb = 0C to +70C VCC = +5.0V 10% CL= 50pF, RL = 500 MIN 4.0 4.0 0 0 4.0 10.0 0 0 4.0 6.0 MAX ns ns ns ns ns UNIT AC WAVEFORMS For all waveforms, VM = 1.5V.
