74F537

Philips Semiconductors Product specification 1-of-10 decoder (3-State) 74F537 DESCRIPTION The 74F537 is a one-of-ten decoder/demultiplexer with four active High BCD inputs and ten mutually exclusive outputs. A Polarity control (P) input determines whether the outputs are active Low or active High. The 74F537 has 3-State outputs and a High signal on the Output Enables (OE) input forces all outputs to the high impedance state. Two input Enables, active High (E1) and active Low (E0), are available for demultiplexing data to the selected output in either non-inverted or inverted form. Input codes greater than BCD nine causes all outputs to go to the inactive state (i.e., same polarity as the P input).

For conditions shown as MIN or MAX, use the appropriate value under the 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 should be performed last. 1989 Jan 20 3 Philips Semiconductors Product specification 1-of-10 decoder (3-State) 74F537 AC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL PARAMETER TEST CONDITIONS Tamb = +25°C VCC = +5.0V CL = 50pF, RL = 500Ω MIN tPLH tPHL tPLH tPHL tPLH tPHL tPLH tPHL tPZH tPZL tPHZ tPLZ Propagation delay An to Qn Propagation delay E0 to Qn Propagation delay E1 to Qn Propagation delay P to Qn Output Enable time OE to Qn Output Disable time OE to Qn Waveform 1 Waveform 2 Waveform 2 Waveform 1 Waveform 3 Waveform 4 Waveform 3 Waveform 4 4.5 3.0 4.0 3.0 6.0 4.0 5.0 3.5 2.5 4.0 1.5 2.0 TYP 9.0 7.5 8.0 8.0 8.5 8.5 12.5 6.5 4.5 5.5 3.0 4.0 MAX 14.0 11.0 11.0 11.0 11.5 11.5 16.0 10.0 7.0 8.0 6.0 6.5 Tamb = 0°C to +70°C VCC = +5.0V ± 10% CL = 50pF, RL = 500Ω MIN 4.5 3.0 4.0 3.0 6.0 4.0 5.0 3.5 2.5 4.0 1.0 2.0 MAX 16.0 12.0 12.0 12.0 13.0 12.5 17.0 11.0 8.0 9.0 7.0 7.0 ns ns ns ns ns ns ns ns ns ns ns ns UNIT AC WAVEFORMS For all waveforms, VM = 1.5V.
