INTEGRATED CIRCUITS 74F253 Dual 4-bit input multiplexer (3-State) Product specification IC15 Data Handbook 1988 Nov 29 Philips Semiconductors Product specification Dual 4-input multiplexer (3-State) 74F253 FEATURES PIN CONFIGURATION • 3-State outputs for bus interface and multiplex expansion • Common select inputs • Separate Output Enable Inputs DESCRIPTION The 74F253 has two identical 4-input multiplexers with 3-State outputs which select two bits from four sources selected by common Select inputs (S0, S1). When the individual Output Enable (OEa, OEb) inputs of the 4-input multiplexers are High, the outputs are forced to a high impedance (Hi-Z) state.

To avoid exceeding the maximum current ratings when the outputs of the 3-State devices are tied together, all but one device must be in the high-impedance state. Therefore, only one Output Enable must be active at a time.

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. 1988 Nov 29 5 Philips Semiconductors Product specification Dual 4-input multiplexer (3-State) 74F253 AC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL TEST CONDITION PARAMETER VCC = +5V ± 10% Tamb = 0°C to +70°C CL = 50pF RL = 500Ω VCC = +5V Tamb = +25°C CL = 50pF RL = 500Ω MIN TYP MAX MIN MAX UNIT tPLH tPHL Propagation delay In to Yn Waveform NO TAG 3.0 3.0 4.5 5.0 7.0 7.0 3.0 3.0 7.5 8.0 ns tPLH tPHL Propagation delay Sn to Yn Waveform NO TAG 4.5 5.0 7.5 8.5 10.5 11.0 4.5 4.5 11.0 12.0 ns tPZH tPZL Output Enable time to High or Low level Waveform 2 Waveform 3 3.0 3.0 6.5 6.5 8.0 8.0 3.0 3.0 9.0 9.0 ns tPHZ tPLZ Output Disable time from High or Low level Waveform 2 Waveform 3 2.5 2.0 3.5 3.0 5.0 5.0 2.0 1.5 6.0 6.0 ns AC WAVEFORMS For all waveforms, VM = 1.5V In, Sn VM OEn VM tPLH VM Yn VM VM tPZH tPHZ VOH –0.3V Yn VM 0V SF00804 Waveform 2. 3-State Output Enable Time to High Level and Output Disable Time from High Level 1988 Nov 29 VM VOL +0.3V Waveform 3. 3-State Output Enable Time to Low Level and Output Disable Time from Low Level Waveform 1.
