SN74LVC373AGQNR - Texas Instruments Octal Transparent D-Type Latches

The SN74LVC373AGQNR from Texas Instruments is a high-performance, octal transparent D-type latch with a wide operating voltage range and the capability to drive up to 24mA at the output. This integrated circuit is designed for 2-V to 3.6-V VCC operation, making it suitable for interfacing with 3.3-V logic in mixed 3.3-V/5-V systems.

Each latch in the SN74LVC373AGQNR has a 3-state output that can be used in bus-oriented applications. The device features eight latches with three-state outputs for bus organized system applications. The latches are transparent D-type latches, meaning 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 significant feature of this product is its support for 5-V tolerant inputs, which allows for direct interfacing with 5-V TTL logic without the need for additional level shifting. This makes the SN74LVC373AGQNR a versatile choice for modern mixed-voltage systems.

The device also offers a wide range of features that enhance its performance and ease of use, including:

• Max tpd of 4.6 ns at 3.3 V
• Low power consumption, with a typical ICC of only 20 μA
• Support for mixed-mode voltage operation on all ports
• IEC-61000-4-2 Level 4 ESD protection
• Latch-up performance exceeds 100 mA per JESD 78, Class II

Offered in a compact, 20-pin QFN package, the SN74LVC373AGQNR is designed to minimize board space while providing robust latch functionality for a variety of applications, including data storage, addressable latch, and as a buffer for data lines. With its industry-standard footprint, this component is an excellent choice for designers looking for a reliable and high-performance solution for their digital systems.

Overall, the SN74LVC373AGQNR is a testament to Texas Instruments' commitment to providing advanced logic solutions that meet the evolving needs of modern electronics.
