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. 1990 Aug 30 5 Philips Semiconductors Product specification Transceivers 74F242/74F243 AC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL VCC = +5V ± 10% Tamb = 0°C to +70°C CL = 50pF, RL = 500Ω VCC = +5V Tamb = +25°C CL = 50pF, RL = 500Ω TEST CONDITION PARAMETER UNIT MIN TYP MAX MIN MAX Waveform NO TAG 2.5 2.0 3.5 3.0 6.0 4.5 2.5 2.0 7.0 4.5 ns Waveform 3 Waveform 4 3.0 3.5 4.0 6.5 7.0 9.0 3.0 3.5 8.0 10.5 ns tPLH tPHL Propagation delay An, Bn to Bn, An tPZH tPZL Output Enable time to High or Low level tPHZ tPLZ Output Disable time from High or Low level Waveform 3 Waveform 4 3.5 3.5 5.5 6.0 8.5 9.5 3.5 3.5 9.0 11.0 ns tPLH tPHL Propagation delay An, Bn to Bn, An Waveform 2 2.5 2.5 4.0 4.0 5.2 5.2 2.0 2.0 6.2 6.5 ns tPZH tPZL Output Enable time to High or Low level Waveform 3 Waveform 4 2.0 2.0 4.5 5.0 5.7 7.5 2.0 2.0 6.7 8.5 ns tPHZ tPLZ Output Disable time from High or Low level Waveform 3 Waveform 4 2.0 2.0 4.0 4.5 6.0 6.0 2.0 2.0 7.0 7.0 ns 74F242 74F243 AC WAVEFORMS For all waveforms, VM = 1.5V.
