SN74HC573N

The SN74HC573N is a high-performance CMOS octal D-type transparent latch with 3-state outputs. It features eight independent D-type latches, each with a dedicated data input (D), a latch enable input (LE), and a 3-state output. The latch enable input allows the latch to store the data present at the D input when it is asserted (high or low, depending on the specific configuration). The 3-state outputs can be controlled via an output enable (OE) pin, which places the outputs in a high-impedance state when not in use, preventing interference with other devices on the bus line.

The SN74HC573N operates within a supply voltage range of 2V to 6V, making it suitable for a variety of applications with different power supply requirements. It offers fast propagation delays and low power consumption, making it an ideal choice for high-frequency digital circuits. The IC is packaged in a plastic DIP (dual in-line package) with 20 pins, allowing for easy integration into existing circuits.

The SN74HC573N is functionally compatible with low-power Schottky TTL (LSTTL) devices and complies with JEDEC standard no. 7A. It is pin-compatible with other devices in the 74HC series, making it easy to replace or upgrade existing circuits.

Overall, the SN74HC573N is a versatile, high-performance CMOS octal D-type transparent latch with 3-state outputs that offers low power consumption, wide operating voltage range, and input protection. Its compact package and pin compatibility make it an excellent choice for use in digital systems where reliable data latching and precise timing control are essential.
