The LVTH162244 devices are 16-bit buffers and line drivers designed for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment. These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide true outputs and symmetrical active-low output-enable (OE) inputs. The outputs, which are designed to source or sink up to 12 mA, include equivalent 22-Ω series resistors to reduce overshoot and undershoot.

FEATURES
• Members of the Texas Instruments Widebus™
   Family
• Output Ports Have Equivalent 22-Ω Series
   Resistors, So No External Resistors Are
   Required
• Support Mixed-Mode Signal Operation (5-V
   Input and Output Voltages With 3.3-V VCC)
• Support Unregulated Battery Operation Down
   to 2.7 V
• Typical VOLP (Output Ground Bounce) <0.8 V
   at VCC = 3.3 V, TA = 25°C
• Ioff and Power-Up 3-State Support Hot
   Insertion
• Bus Hold on Data Inputs Eliminates the Need
   for External Pullup/Pulldown Resistors
• Distributed VCC and GND Pins Minimize
   High-Speed Switching Noise
• Flow-Through Architecture Optimizes PCB
   Layout
• Latch-Up Performance Exceeds 500 mA Per
   JESD 17
• ESD Protection Exceeds JESD 22
   – 2000-V Human-Body Model (A114-A)
   – 200-V Machine Model (A115-A)
