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 = 5 V, 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. 2004 Feb 25 4 Philips Semiconductors Product data Octal inverting buffer 74F240 AC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL PARAMETER Tamb = +25 °C VCC = +5.0 V CL = 50 pF; RL = 500 Ω TEST CONDITION Tamb = 0 °C to +70 °C VCC = +5.0 V ± 10% CL = 50 pF; RL = 500 Ω MIN TYP MAX MIN MAX Waveform 1 3.0 2.0 4.5 3.0 6.5 4.5 3.0 2.0 7.5 5.0 ns Output enable time to high or low level Waveform 2 & 3 3.0 4.5 5.0 6.5 7.5 8.5 3.0 4.0 9.0 10.0 ns Output disable time from high or low level Waveform 2 & 3 3.0 3.0 5.5 5.0 7.0 7.0 3.0 3.0 7.5 7.5 ns tPLH tPHL Propagation delay Ian, Ibn to Yn tPZH tPZL tPHZ tPLZ NOTES: 1. | tPN actual – tPM actual| for any output compared to any other output where N and M are either LH or HL. 2004 Feb 25 UNIT 5 Philips Semiconductors Product data Octal inverting buffer 74F240 AC WAVEFORMS Ian, Ibn VM OEn VM VM VM OEb tPHL tPLH VM Yn tPZL VM tPLZ 3.5V VM Yn, Yn SF00328 VOL +0.3V SF00331 Waveform 1.
