INTEGRATED CIRCUITS 74F157A, 74F158A Data selectors/multiplexers Product specification Supersedes data of 1996 Mar 12 IC15 Data Handbook 2000 Jun 30 Philips Semiconductors Product specification Data selectors/multiplexers 74F157A: 74F158A: 74F157A, 74F158A Quad 2-input data selector/multiplexer, non-inverting Quad 2-input data selector/multiplexer, inverting • Industrial temperature range (–10°C to +85°C) available for DESCRIPTION The 74F157A is a high speed Quad 2-Input Multiplexer which selects 4 bits of data from one of two sources under the control of a common Select input (S). The Enable input (E) is active when Low. When E is High, all of the outputs (Yn) are forced Low regardless of all other input conditions. 74F157A Moving data from two registers to a common output bus is a common use of the 74F157A. The state of the Select input determines the particular register from which the data comes. TYPE TYPICAL PROPAGATION DELAY TYPICAL SUPPLY CURRENT (TOTAL) 74F157A 4.6ns 15mA 74F158A 3.7ns 10mA The device is the logic implementation of a 4-pole, 2-position switch where the position of the switch is determined by the logic levels supplied to the Select input. The 74F158A is similar, but has inverting outputs (Yn).

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. 4. ICC is measured with 4.5V applied to all inputs and all outputs open. 2000 Jun 30 4 Philips Semiconductors Product specification Data selectors/multiplexers 74F157A, 74F158A AC ELECTRICAL CHARACTERISTICS FOR 74F157A AND 74F158A LIMITS SYMBOL VCC = +5.0V ± 10% Tamb = 0°C to +70°C CL = 50pF RL = 500Ω VCC = +5.0V Tamb = +25°C CL = 50pF RL = 500Ω TEST CONDITION PARAMETER VCC = +5.0V ± 10% Tamb = –40°C to +85°C CL = 50pF RL = 500Ω UNIT MIN TYP MAX MIN MAX MIN MAX Waveform 1 3.5 2.5 4.5 3.5 6.5 5.0 3.0 1.5 7.0 6.0 3.0 1.5 7.5 6.5 ns Waveform 3 6.0 4.0 7.5 5.0 9.0 6.5 5.5 4.0 10.5 7.0 5.5 4.0 11.0 7.5 ns tPLH tPHL Propagation delay I0n, I1n to Yn tPLH tPHL Propagation delay E to Yn tPLH tPHL Propagation delay S to Yn Waveform 1 5.5 4.5 7.5 6.0 10.0 7.5 5.0 4.0 11.0 8.5 5.0 4.0 11.5 9.0 ns tPLH tPHL Propagation delay I0n, I1n to Yn Waveform 2 3.0 1.5 4.0 2.5 6.0 4.0 2.5 1.0 7.0 4.5 — — ns tPLH tPHL Propagation delay E to Yn Waveform 4 4.5 5.0 5.5 6.0 7.0 7.5 4.0 5.0 7.5 8.0 — — ns tPLH tPHL Propagation delay S to Yn Waveform 2 4.5 4.0 6.5 5.5 8.5 7.5 4.0 3.5 9.5 8.0 — — ns 74F157A 74F158A AC WAVEFORMS For all waveforms, VM = 1.5V I0n, I1n, S I0n, I1n, S VM tPHL tPLH VM Yn VM VM VM tPLH VM tPHL VM Yn VM SF00221 Waveform 1.
