SN54ALVTH162244 Datasheet, PDF (1/13 Pages) Texas Instruments – 2.5-V/3.3-V 16-BIT BUFFERS/DRIVERS WITH 3-STATE OUTPUTS

D State-of-the-Art Advanced BiCMOS
Technology (ABT) Widebus ™ Design for
2.5-V and 3.3-V Operation and Low Static
Power Dissipation
D Support Mixed-Mode Signal Operation (5-V
Input and Output Voltages With 2.3-V to
3.6-V V_CC )
D Typical V_OLP (Output Ground Bounce)
< 0.8 V at V_CC = 3.3 V, T_A = 25°C
D Power Off Disables Outputs, Permitting
Live Insertion
D High-Impedance State During Power Up
and Power Down Prevents Driver Conflict
D Uses Bus Hold on Data Inputs in Place of
External Pullup/Pulldown Resistors to
Prevent the Bus From Floating
D Output Ports Have Equivalent 30-Ω Series
Resistors, So No External Resistors Are
Required
D Auto3-State Eliminates Bus Current
Loading When Output Exceeds V_CC + 0.5 V
D Latch-Up Performance Exceeds 250 mA Per
JESD 17
D ESD Protection Exceeds 2000 V Per
MIL-STD-883, Method 3015; Exceeds 200 V
Using Machine Model; and Exceeds 1000 V
Using Charged-Device Model, Robotic
Method
D Flow-Through Architecture Facilitates
Printed Circuit Board Layout
D Distributed V_CC and GND Pin Configuration
Minimizes High-Speed Switching Noise
D Package Options Include Plastic Shrink
Small-Outline (DL), Thin Shrink
Small-Outline (DGG), Thin Very
Small-Outline (DGV) Packages, and 380-mil
Fine-Pitch Ceramic Flat (WD) Package
NOTE: For order entry:
The DGG package is abbreviated to G, and
the DGV package is abbreviated to V.
