Texas Instruments SN74LV74A/SN74LV74A-Q1 Dual D-Type Flip-Flops

Texas Instruments SN74LV74A/SN74LV74A-Q1 Dual D-Type Flip-Flops are positive-edge-triggered D-type flip-flops designed for 2V to 5.5V VCC operation. These devices are fully specified for partial-power-down applications using Ioff. When powered down, the Ioff circuitry disables the outputs, preventing damaging current backflow through the devices. The SN74LV74A-EP devices have gold bond wires, a temperature range of –55 to +105°C, and an SnPb lead finish. The Texas Instruments SN74LV74A-Q1 devices are AEC-Q100 qualified for automotive applications.
