Product Overview: SN74ABT373DBRG4

The SN74ABT373DBRG4 is a high-performance, octal transparent D-type latch designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This integrated circuit is part of the ABT family, which is known for its advanced bi-CMOS technology, offering both high-speed operation and the ability to drive heavily loaded outputs with minimal power consumption.

The SN74ABT373DBRG4 operates as a latch with eight data inputs (D0-D7), eight outputs (Q0-Q7), and a common Latch Enable (LE) input. When LE is high, the outputs follow the inputs, behaving as a transparent latch. However, when LE goes low, the output will hold the last data presented prior to the transition, regardless of further changes to the input data lines. This feature makes the device ideal for capturing and holding data at a specific moment in time.

Additionally, this product includes an Output Enable (OE) feature, which allows the user to place the eight outputs in either a normal logic state or a high-impedance state. When OE is high, the outputs are disabled and in a high-impedance state, which effectively disconnects them from the bus or system they are connected to. This is particularly useful in bus-oriented systems where multiple devices need to share the same data lines.

The SN74ABT373DBRG4 operates over a broad supply voltage range from 4.5V to 5.5V, making it compatible with many 5V systems. It also features fast propagation delays and setup times, which are critical for high-speed applications. The device is packaged in a 20-pin SSOP (Shrink Small Outline Package), which is both space-efficient and suitable for automated surface-mount assembly processes.

With its robust latch function, bus-friendly interface, and high-speed operation, the SN74ABT373DBRG4 is a versatile component that can be used in a wide range of applications, including data storage, communication systems, computers, and industrial controls. Texas Instruments' commitment to quality ensures that this latch will perform reliably in the most demanding environments.

Whether you are designing a new system or upgrading an existing one, the SN74ABT373DBRG4 from Texas Instruments is an excellent choice for your digital logic needs.
