| Описание: | 74ACQ240 • 74ACTQ240 Quiet SeriesпЈЄ Octal Buffer/Line Driver with 3-STATE Outputs July 1989 Revised November 1999 74ACQ240 • 74ACTQ240 Quiet SeriesпЈЄ Octal Buffer/Line Driver with 3-STATE Outputs General The ACQ/ACTQ240 is an inverting octal buffer and line driver designed to be employed as a memory address driver, clock driver and bus oriented transmitter or receiver which provides improved PC board density. The ACQ/ ACTQ utilizes Fairchild’s Quiet SeriesпЈЄ technology to guarantee quiet output switching and improve dynamic threshold performance. FACT Quiet SeriesпЈЄ features GTOпЈЄ output control and undershoot corrector in addition to a split ground bus for superior performance. Features s ICC and IOZ reduced by 50% s Guaranteed simultaneous switching noise level and dynamic threshold performance s Guaranteed pin-to-pin skew AC performance s Improved latch-up immunity s Inverting 3-STATE outputs drive bus lines or buffer memory address registers s Outputs source/sink 24 mA s Faster prop delays than the standard ACT240 Ordering Code: Order Number 74ACQ240SC 74ACQ240SJ 74ACQ240PC 74ACTQ240SC 74ACTQ240SJ 74ACTQ240QSC Package Number M20B M20D N20A M20B M20D MQA20 Package 20-Lead Small Outline Integrated Circuit (SOIC)JEDEC MS-013, 0.300” Wide Body 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide 20-Lead Small Outline Integrated Circuit (SOIC)JEDEC MS-013, 0.300” Wide Body 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Quarter Size Outline Package (QSOP), JEDEC MO-137, 0.150” Wide Device also available in Tape and Reel.
