INTEGRATED CIRCUITS 74F154 1-of-16 decoder/demultiplexer Product specification IC15 Data Handbook 1990 Jan 08 Philips Semiconductors Product specification Decoder/demultiplexer 74F154 FEATURES ORDERING INFORMATION • 16-line demultiplexing capability • Mutually exclusive outputs • 2-input enable gate for strobing or expansion COMMERCIAL RANGE VCC = 5V ±10%, Tamb = 0°C to +70°C PKG DWG # 24-pin plastic Slim DIP (300mil) N74F154N SOT222-1 24-pin plastic SOL N74F154D SOT137-1 DESCRIPTION DESCRIPTION The 74F154 decoder accepts four active High binary address inputs and provides 16 mutually exclusive active Low outputs. The 2-input Enable (E0, E1) gate can be used to strobe the decoder to eliminate the normal decoding “glitches” on the outputs, or it can be used for expansion of the decoder. The enable gate has two AND’ed inputs which must be Low to enable the outputs. PIN CONFIGURATION The 74F154 can be used as 1-of-16 demultiplexer by using one of the Enable inputs as the multiplexed data input. When the other Enable is Low, the addressed output will follow the state of the applied data.

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 Jan 08 4 Philips Semiconductors Product specification Decoder/demultiplexer 74F154 AC ELECTRICAL CHARACTERISTICS 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 MIN TYP MAX MIN MAX UNIT tPLH tPHL Propagation delay An to Qn Waveform 1 2.0 3.5 5.0 6.5 9.5 10.0 1.5 3.0 10.5 10.5 ns tPLH tPHL Propagation delay En to Qn Waveform 2 2.0 4.0 4.0 6.0 7.5 9.0 1.5 3.5 8.0 9.5 ns AC WAVEFORMS For all waveforms, VM = 1.5V.
