Product Description

The MC74ACT373ML1 features eight D-type latches with three-state outputs. The latches are transparent, which means that when the Latch Enable (LE) input is HIGH, the Q outputs will follow the data (D) inputs. When LE is taken LOW, the data that meets the setup-time requirements is latched. The Output Enable (OE) input, when LOW, places the eight outputs in a normal state; when OE is HIGH, the outputs go into the high impedance state, which effectively isolates the outputs from the bus line.

The device provides high-speed operation with a propagation delay of typically 4.5 ns at a supply voltage of 5V, which is particularly beneficial for fast data processing systems. It also features a low ICCP, which minimizes power consumption and makes it suitable for power-sensitive applications. The MC74ACT373ML1 is supplied in a 20-pin SOIC package, which is widely used in the industry and is compatible with standard surface-mount technology (SMT) processes.

ON Semiconductor's commitment to quality and performance is evident in the MC74ACT373ML1, making it a reliable choice for designers and engineers looking for a latch that combines speed, power efficiency, and a wide operating temperature range.
