16-BIT BUFFER/DRIVER
WITH 3-STATE OUTPUTS
SCES065F – JANUARY 1996 – REVISED OCTOBER 2004
Member of the Texas Instruments Widebus™
Family
EPIC™ (Enhanced-Performance Implanted
CMOS) Submicron Process
Output Ports Have Equivalent 26-
Ω Series
Resistors, So No External Resistors Are
Required
ESD Protection Exceeds 2000 V Per
MIL-STD-883, Method 3015; Exceeds 200 V
Using Machine Model (C = 200 pF, R = 0)
Latch-Up Performance Exceeds 250 mA Per
JESD 17
Bus Hold on Data Inputs Eliminates the Need
for External Pullup/Pulldown Resistors
Package Options Include Plastic 300-mil
Shrink Small-Outline (DL) and Thin Shrink
Small-Outline (DGG) Packages
NOTE: For tape-and-reel order entry, the DGGR package is
abbreviated to GR.
This 16-bit buffer/driver is designed for 1.65-V to
3.6-V VCC operation.
The SN74ALVCH162244 is designed specifically to
improve the performance and density of 3-state
memory

drivers,
clock
drivers,
and
bus-oriented receivers and transmitters.
symmetrical active-low output-enable (OE) inputs.
The outputs, which are designed to sink up to 12 mA, include equivalent 26-
Ω resistors to reduce overshoot and
undershoot.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH162244 is characterized for operation from -40
°C to 85°C.
