(1) All typical values are at VCC = 3.3 V, TA = 25°C.
(2) This is the bus-hold maximum dynamic current. It is the minimum overdrive current required to switch the input from one state to
another.
(3) On products compliant to MIL-PRF-38535, this parameter is not production tested.
(4) This is the increase in supply current for each input that is at the specified TTL voltage level, rather than VCC or GND.

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 V CC = 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)
