DESCRIPTION/ORDERING INFORMATION
This hex buffer gate is operational at 0.8-V to 2.7-V V_CC, but is designed specifically for 1.65-V to 1.95-V V_CC
operation.
The SN74AUC34 performs the Boolean function Y = A.
This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
