General description

The 74LVT573 is a high-performance BiCMOS product designed for VCC operation at 3.3 V. This device is an octal transparent latch coupled to eight 3-state output buffers. The two sections of the device are controlled independently by Latch Enable (LE) and Output Enable (OE) control gates. The 74LVT573 has a broadside pinout configuration to facilitate PC board layout and allow easy interface with microprocessors.
