74LVC273A数据手册集成电路（IC）的触发器规格书PDF

描述 Description

The 74LVC273A provides eight positive-edge-triggered D-type flip-flops with a direct clear (CLR) input.

\tThe device is designed for operation with a power supply range of 1.65V to 3.6V. The device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output preventing damaging current backflow when the device is powered down.
