– 2000-V Human-Body Model (A114-A)  
– 200-V Machine Model (A115-A)  
•
Dynamic Drive Capability Is Equivalent to  
Standard Outputs With IOH and IOL of ±24 mA  
at 2.5-V VCC  
•
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.

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.
