5-V VCC SN74AVC16334 16-BIT UNIVERSAL BUS DRIVER WITH 3-STATE OUTPUTS SCES154I – DECEMBER 1998 – REVISED MAY 2005 • Overvoltage-Tolerant Inputs/Outputs Allow Mixed-Voltage-Mode Data Communications • Ioff Supports Partial-Power-Down Mode Operation • ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) – 200-V Machine Model (A115-A) • Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II DESCRIPTION A Dynamic Output Control (DOC™) circuit is implemented, which, during the transition, initially lowers the output impedance to effectively drive the load and, subsequently, raises the impedance to reduce noise.
Figure 1 shows typical VOL vs IOL and VOH vs IOH curves to illustrate the output impedance and drive capability of the circuit.
At the beginning of the signal transition, the DOC circuit provides a maximum dynamic drive that is equivalent to a high-drive standard-output device.
For more information, refer to the TI application reports, AVC Logic Family Technology and Applications, literature number SCEA006, and Dynamic Output Control (DOC™) Circuitry Technology and Applications, literature number SCEA009.
