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. Features s Input and output interface capability to systems at 5V VCC s Bushold on the data inputs eliminate the need for external pull-up resistors to hold unused inputs s Outputs source/sink 32 mA/64 mA s Functionally compatible with the 74 series 273 s Latch-up performance exceeds 500 mA s ESD performance: Human-body model ! 2000V Machine model ! 200V Charged-device model ! 1000V Ordering Code: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Pb-Free package per JEDEC J-STD-020B. Note 1: “_NL” indicates Pb-Free package (per JEDEC J-STD-020B).
