SN74ALVTHR16245 Datasheet, PDF (1/15 Pages) Texas Instruments – 2.5-V/3.3-V 16-BIT BUS TRANSCEIVERS 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 High Drive (–12/12 mA at 3.3-V V_CC)
D I_off and Power-Up 3-State Support Hot
Insertion
D Use 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 Flow-Through Architecture Facilitates
Printed Circuit Board Layout
D Distributed V_CC and GND Pins Minimize
High-Speed Switching Noise
D Latch-Up Performance Exceeds 100 mA Per
JESD 78, Class II
D ESD Protection Exceeds JESD 22
