Working Principles

The MC74ACT373DW operates as an octal transparent latch with 3-state outputs. When the latch enable (LE) signal is high, the data inputs (D0-D7) are latched to the outputs (Q0-Q7). The outputs can be disabled by setting the output enable (OE) signal low, which puts them in a high-impedance state.

This latch operates at high speeds, allowing for efficient data transfer between different parts of a digital system. It is compatible with TTL logic levels, making it suitable for use in various applications. The wide operating voltage range ensures compatibility with different power supply voltages, while the low power consumption helps conserve energy in battery-powered devices.
