Product Description

The 54ACTQ373FMQB is engineered for high-speed operation while driving capacitive loads. The device is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working memory. The octal transparent nature of the latch means that while 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 that were set up at the D inputs.

A notable feature of the 54ACTQ373FMQB is its Quiet Series™ technology, which significantly reduces the noise created by voltage transitions. By incorporating this technology, the device is ideal for use in noise-sensitive environments like telecommunication and computing systems where signal integrity is paramount.

The device also features a bus-hold circuitry that eliminates the need for external pull-up or pull-down resistors, simplifying board design and reducing board space requirements. The 3-state outputs ensure that multiple units can be connected to the same bus, allowing for bus expansion with ease.

With its robust and versatile design, the 54ACTQ373FMQB from Texas Instruments stands out as a reliable choice for designers looking to incorporate a military-grade, high-speed octal latch in their systems.
