STMicroelectronics M74HC573 Octal D-Type Latch IC, DIP-20

The STMicroelectronics M74HC573 is a high-speed CMOS octal latch featuring 3-state outputs, manufactured using silicon gate C²MOS technology. This 8-bit D-type latch is controlled by a latch enable input (LE) and an output enable input (OE). When the LE input is held high, the Q outputs follow the data inputs precisely; when LE goes low, the outputs are latched at the exact logic level of the D inputs. The OE input, when low, allows the outputs to operate in a normal high or low logic state, and when high, places the outputs in a high-impedance state, making this IC ideal for bus-organised systems.

All inputs are protected against static discharge and transient excess voltages, ensuring robust performance. The DIP-20 package provides easy through-hole mounting for prototyping and PCB designs. With a wide supply voltage range from -0.5V to 7V and an output current capability of 35mA, this latch IC is versatile for various digital logic applications.

The octal configuration and 3-state outputs simplify bus design, allowing multiple devices to share a common data line. The 74HC family ensures low power consumption and high noise immunity, making it a reliable choice for both commercial and industrial electronic projects.
