SN74AVC16834 18-BIT UNIVERSAL BUS DRIVER WITH 3-STATE OUTPUTS www.ti.com SCES183H – DECEMBER 1998 – REVISED JUNE 2005 • FEATURES • • • Member of the Texas Instruments Widebus™ Family DOC™ (Dynamic Output Control) Circuit Dynamically Changes Output Impedance, Resulting in Noise Reduction Without Speed Degradation Dynamic Drive Capability Is Equivalent to Standard Outputs With IOH and IOL of ±24 mA at 2.5-V VCC 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/ORDERING INFORMATION 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. 3.2 TA = 25°C Process = Nominal - Output Voltage - V 2.8 2.4 VCC = 3.3 V 2.0 1.6 VCC = 2.5 V 1.2 OH VCC = 1.8 V 0.8 V VOL - Output Voltage - V 2.8 TA = 25°C Process = Nominal 2.4 2.0 1.6 1.2 0.8 VCC = 3.3 V 0.4 0.4 0 17 34 51 68 85 102 119 IOL - Output Current - mA 136 153 170 VCC = 2.5 V VCC = 1.8 V -160 -144 -128 -112 -96 -80 -64 -48 IOH - Output Current - mA -32 -16 0 Figure 1. Output Voltage vs Output Current This 18-bit universal bus driver is operational at 1.2-V to 3.6-V VCC, but is designed specifically for 1.65-V to 3.6-V VCC operation. Data flow from A to Y is controlled by the output-enable (OE) input. The device operates in the transparent mode when the latch-enable (LE) input is low. The A data is latched if the clock (CLK) input is held at a high or low logic level. If LE is high, the A data is stored in the latch/flip-flop on the low-to-high transition of CLK. When OE is high, the outputs are in the high-impedance state. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
