STMicroelectronics 74LVC573AMTR Octal D-Type Transparent Latch

The 74LVC573AMTR from STMicroelectronics is a high-performance, low-voltage CMOS octal D-type transparent latch designed for use in 3.3V LVC logic circuits. This IC is tailored for use in applications that require the capture and retention of data during a transient period. It is a perfect solution for temporary storage of data, buffering, and for implementing memory address latching in computing and digital systems.

With its wide operating voltage range of 1.65V to 3.6V, the 74LVC573AMTR ensures compatibility with lower voltage systems, while also providing interface capabilities with 5V logic levels, thanks to its 5V tolerant inputs. This makes it an ideal choice for interfacing with both legacy and modern digital systems, ensuring a smooth transition in mixed-voltage environments.

The device features eight latches with 3-state outputs. When the latch enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs. A further feature of this device is the 3-state output control input (OE). When OE is high, the outputs are in a high-impedance state, which is particularly useful for creating bus-oriented systems where multiple outputs can share a connection line without interference.

Designed for high-speed operation, the 74LVC573AMTR can support data rates up to several tens of MHz, which is essential for high-speed data processing and computing applications. Its robust design also includes latch-up performance that exceeds 250mA per JESD 17, which provides additional protection against latch-up phenomena during high-speed or high-voltage conditions.

STMicroelectronics packages the 74LVC573AMTR in a TSSOP20 (Thin Shrink Small Outline Package) which offers a reduced footprint on PCBs (Printed Circuit Boards), making it suitable for space-constrained applications. The product is also available in tape and reel packaging, simplifying the manufacturing process by ensuring compatibility with automated placement machines.

Overall, the 74LVC573AMTR is a versatile, reliable, and high-performing component that meets the needs of modern digital logic applications requiring temporary data storage with the quality and reliability expected from STMicroelectronics.
