描述 Description

The MC74LVX573 is an advanced high speed CMOS octal latch with 3-state outputs. The inputs tolerate voltages up to 7V, allowing the interface of 5V systems to 3V systems. This 8-bit D-type latch is controlled by a latch enable input and an output enable input. When the output enable input is high, the eight outputs are in a high impedance state.
