? semiconductor components industries, llc, 2011 june, 2011 ? rev. 10 1 publication order number: mc74hct574a/d mc74hct574a octal 3-state noninverting d flip-flop with lsttl-compatible inputs high ? performance silicon ? gate cmos the mc74hct574a is identical in pinout to the ls574. this device may be used as a level converter for interfacing ttl or nmos outputs to high speed cmos inputs. data meeting the setup time is clocked to the outputs with the rising edge of the clock. the output enable input does not affect the states of the flip ? flops, but when output enable is high, all device outputs are forced to the high ? impedance state. thus, data may be stored even when the outputs are not enabled. the hct574a is identical in function to the hct374a but has the flip ? flop inputs on the opposite side of the package from the outputs to facilitate pc board layout. features ? output drive capability: 15 lsttl loads ? ttl nmos compatible input levels ? outputs directly interface to cmos, nmos and ttl ? operating voltage range: 4.5 to 5.5 v ? low input current: 1.0 a ? in compliance with the requirements defined by jedec standard no. 7 a ? chip complexity: 286 fets or 71.5 equivalent gates ? these devices are pb ? free and are rohs compliant http://onsemi.com marking diagrams soic ? 20 dw suffix case 751d hct574a awlyywwg 1 20 1 see detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet. ordering information pdip ? 20 n suffix case 738 1 20 mc74hct574an awlyywwg 1 1 20 hct 574a alyw tssop ? 20 dt suffix case 948e 1 a = assembly location wl, l = wafer lot yy, y = year ww, w = work week g or =pb ? free package (note: microdot may be in either location)
