Product Description

The MC74HCT573AN device from ON Semiconductor is an advanced octal latch that is capable of storing eight bits of data. Each latch has three-state outputs designed for bus-oriented applications. The device features a transparent mode, where the latches remain transparent to the data when Latch Enable (LE) is high, and data that appears on the inputs passes through to the outputs. When LE is taken low, the data that was present on the inputs at the time of the transition is latched.

Designed to be used in conjunction with bus driving systems, the MC74HCT573AN's outputs will be in a high-impedance state when the Output Enable (OE) is high. This allows for the outputs to be tied together without causing conflicts on the bus lines. The device is compatible with both CMOS and TTL logic levels, ensuring easy integration into various systems without the need for additional interfacing components.

The MC74HCT573AN operates over a broad voltage range of 4.5V to 5.5V and offers a high-speed performance, with a typical propagation delay time of only 15ns at a supply voltage of 5V. It is packaged in a 20-pin DIP (Dual In-line Package), suitable for through-hole mounting, thus facilitating easy installation on printed circuit boards.

With its wide operating temperature range of -55°C to 125°C, the MC74HCT573AN is designed to withstand extreme conditions, making it ideal for industrial and automotive applications where reliability and durability are critical.

ON Semiconductor's commitment to quality ensures that the MC74HCT573AN octal latch is a dependable component for digital storage and data retention applications in various electronic systems.
