Product Overview: SN74ACT573PW from Texas Instruments

The SN74ACT573PW is an octal transparent D-type latch with 3-state outputs, designed and manufactured by the renowned semiconductor company, Texas Instruments (TI). This integrated circuit is part of the 74ACT family, which is known for its high-speed CMOS logic. The SN74ACT573PW is specifically designed to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

Constructed with an 8-bit structure, this device features eight latches with 3-state outputs for bus organized systems applications. Each latch is D-type, meaning it captures the state of the data input one setup time before the latch-enable (LE) input falls. When LE is held high, the outputs follow the inputs. When LE is low, the outputs are latched to retain the data that was set up. The OE (Output Enable) bar input, when low, places the eight outputs in a transparent or "on" state, and when high, the outputs are in the high-impedance state, which is essential for interfacing with bus lines in a bus-organized system.

The SN74ACT573PW is characterized for operation from -40°C to 85°C, making it suitable for a wide range of industrial applications. It comes in a TSSOP (Thin Shrink Small Outline Package) with 20 pins, providing a compact footprint for space-constrained applications. This package is designed for surface-mount technology, making it ideal for modern PCB designs.

Key features of the SN74ACT573PW include a wide operating voltage range of 4.5V to 5.5V, low input current of 1µA max, and typical tpd of 9ns. This ensures compatibility with most 5V systems and provides fast response times for critical applications. The device also has a low power consumption, which is critical for energy-efficient designs.

Overall, the SN74ACT573PW from Texas Instruments is a reliable and high-performing component that offers a blend of speed, power efficiency, and a small form factor, making it an excellent choice for a variety of digital applications.
