description (continued)
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.
The SN54LVC374A is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74LVC374A is characterized for operation from –40
°C to 85°C.
