IDT74LVC273A 3.3V CMOS OCTAL D-TYPE FLIP-FLOP WITH RESET INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS OCTAL D-TYPE FLIP-FLOP WITH RESET, POSITIVE EDGE TRIGGER, AND 5 VOLT TOLERANT I/O IDT74LVC273A FEATURES: DESCRIPTION: • 0.5 MICRON CMOS Technology • ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) • VCC = 3.3V ± 0.3V, Normal Range • VCC = 2.7V to 3.6V, Extended Range μ W typ. static) • CMOS power levels (0.4μ • Rail-to-rail output swing for increased noise margin • All inputs, outputs, and I/O are 5V tolerant • Supports hot insertion • Available in SSOP and TSSOP packages The octal D-type flip-flop with reset, positive edge trigger is built using advanced dual metal CMOS technology. This high-speed, low power device is ideal for driving high capacitance loads such as memory address and data buses. All pins can be driven from either 3.3V or 5V devices. This feature allows the use of these devices as translators in a mixed 3.3V/5V supply system. DRIVE FEATURES: • High Output Drivers: ±24mA • Reduced system switching noise APPLICATIONS: • 5V and 3.3V mixed voltage systems • Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM Dx Q D CP Ox CP CLR CLR The IDT logo is a registered trademark of Integrated Device Technology, Inc.
