(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 does not apply.
(4) This is the increase in supply current for each input that is at the specified TTL voltage level, rather than VCC or GND.

DESCRIPTION/ORDERING INFORMATION
The 'LVTH16244A 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.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.

FEATURES
• Members of the Texas Instruments Widebus™ Family
• State-of-the-Art Advanced BiCMOS
   Technology (ABT) Design for 3.3-V Operation and Low Static-Power Dissipation
• 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
• 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)
