description (continued)
When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 2.1 V, OE should be tied to VCC through a pullup resistor
and OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by
the current-sinking/current-sourcing capability of the driver.
The SN54ABT162501 is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74ABT162501 is characterized for operation from –40
°C to 85°C.
