SN74LV373APWRE4 - Texas Instruments

The SN74LV373APWRE4 is a high-performance, octal transparent D-type latch designed by Texas Instruments. This integrated circuit is part of the 74LV family, which operates at a voltage range of 2V to 5.5V, making it suitable for a wide variety of applications that require low-voltage operation and low power consumption.

With its 3-state outputs, the SN74LV373APWRE4 is capable of driving 15 LSTTL loads, which is beneficial for interfacing with bus-oriented systems where bidirectional data flow is necessary. The octal transparent nature of the latch means that while the latch-enable (LE) input is high, the Q outputs will 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 significant feature of this device is the 3-state outputs, which can be placed in a high-impedance state, effectively disconnecting the output from the rest of the circuit. This is particularly useful in multiplexed applications where data needs to be passed without interference from other connected components.

The SN74LV373APWRE4 is housed in a TSSOP (Thin Shrink Small Outline Package) with 20 pins, which provides a compact footprint while still offering ease of integration into various designs. The device is characterized for operation from -40°C to 85°C, ensuring reliability and performance across a broad range of environmental conditions.

Applications for the SN74LV373APWRE4 are diverse and include memory address latching, data storage, and multiplexed data transmission systems. Its low-power operation and high-speed interface capabilities make it an ideal choice for battery-operated devices, portable electronics, and other power-sensitive applications.

Overall, the SN74LV373APWRE4 from Texas Instruments is a versatile and reliable component that provides high-speed latching capabilities with the added benefit of 3-state outputs to facilitate bus-oriented applications. Its compatibility with 5V TTL logic levels and the ability to operate over a wide voltage range make it a flexible solution for designers looking to optimize their digital systems.
