SN74LV27A

SN74LV27A SCES341F – SEPTEMBER 2000 – REVISED JULY 2023 SN74LV27A Triple 3-Input Positive-NOR Gate 1 Features Operation of 2-V to 5.5-V VCC Max tpd of 7 ns at 5 V Typical VOLP (Output Ground Bounce) <0.8 V at VCC = 3.3 V, TA = 25°C Typical VOHV (Output VOH Undershoot) >2.3 V at VCC = 3.3 V, TA = 25°C Ioff Supports Partial-Power-Down Mode Operation Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II 2 Description These triple 3-input positive-NOR gates are designed for 2-V to 5.5-V VCC operation. The SN74LV27A devices perform the Boolean function Y = A + B + C in positive logic. These devices are fully specified for partial-powerdown applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.
