Philips Semiconductors Product specification 74F539Dual 1-of-4 decoder (3-State)

11990 Feb 23 853–1274 98905

DESCRIPTION

The 74F539 contains two independent decoders. Each accepts two address (A0 - A1) input signals and decodes them to select one of four mutually exclusive outputs. A Polarity control (P) input determines whether the outputs are active Low (P=H) or active High (P=L). An active-Low Enable (E ) is available for data demultiplexing. Data is routed to the selected output in non-inverted or inverted form in the active-Low mode or inverted form in the active-High mode. A High signal on the Output Enable (OE n) input forces the 3-State outputs to the high impedance state. TYPE TYPICAL PROPAGATION DELAY TYPICAL SUPPLY CURRENT (TOTAL) 74F539 7.5ns 40mA

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, I OS should be performed last.
