WITH 3-STATE OUTPUTS

SCES079E – JULY 1996 – REVISED DECEMBER 1998
1POST OFFICE BOX 655303 • DALLAS, TEXAS 75265
C0068 State-of-the-Art Advanced BiCMOS
Technology (ABT) Widebus Design for
2.5-V and 3.3-V Operation and Low Static
Power Dissipation
C0068 Support Mixed-Mode Signal Operation (5-V
Input and Output Voltages With 2.3-V to
3.6-V V
CC
)
C0068 Typical V
OLP
(Output Ground Bounce)
<0.8 V at V
CC
= 3.3 V, T
A
= 25°C
C0068 Power Off Disables Outputs, Permitting
Live Insertion
C0068 High-Impedance State During Power Up
and Power Down Prevents Driver Conflict
C0068 Uses Bus Hold on Data Inputs in Place of
External Pullup/Pulldown Resistors to
Prevent the Bus From Floating
C0068 Output Ports Have Equivalent 30-Ω Series
Resistors, So No External Resistors Are
Required
C0068 Auto3-State Eliminates Bus Current
Loading When Output Exceeds V
CC
+ 0.5 V
C0068 Latch-Up Performance Exceeds 250 mA Per
JESD 17
C0068 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
C0068 Flow-Through Architecture Facilitates
Printed Circuit Board Layout
C0068 Distributed V
CC
and GND Pin Configuration
Minimizes High-Speed Switching Noise
C0068 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.
