74LVTH273 Low Voltage Octal D-Type Flip-Flop with Clear 74LVTH273 Low Voltage Octal D-Type Flip-Flop with Clear January 2008 • Input and output interface capability to systems at 5V VCC • Bushold on the data inputs eliminate the need for external pull-up resistors to hold unused inputs • Outputs source/sink • Functionally compatible with the 74 series 273 • Latch-up performance exceeds 500mA • ESD performance: Human-body model > 2000V Machine model > 200V Charged-device model > 1000V The LVTH273 is a high-speed, low-power positive-edgetriggered octal D-type flip-flop featuring separate D-type inputs for each flip-flop. A buffered Clock CP and Clear CLR are common to all flip-flops. The state of each D-type input, one setup time before the positive clock transition, is transferred to the corresponding flip-flop's output. The LVTH273 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs. These octal flip-flops are designed for low-voltage 3.3V VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVTH273 is fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation.
