description (continued)
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 is provided to hold unused or floating data inputs at a valid logic level.
When V
CC
is between 0 and 1.2 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 1.2 V, OE should be tied to V
CC
through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the driver.
All outputs are designed to sink up to 12 mA and include equivalent 30-
resistors to reduce overshoot and
undershoot.
The SN54ALVTH162244 is characterized for operation over the full military temperature range of –55
°
C to
125
°
C. The SN74ALVTH162244 is characterized for operation from –40
°
C to 85
°
C.
