Product Overview: 74AHC373PW from NXP Semiconductors

The 74AHC373PW is a high-speed Si-gate CMOS device manufactured by NXP Semiconductors, known for its robust performance and reliability in a wide range of applications. This particular component is part of the 74AHC family, which is characterized by its low power consumption and high noise immunity, making it an excellent choice for interfacing with other logic families, such as TTL.

The 74AHC373PW is an octal D-type transparent latch featuring 3-state outputs. It is designed to be used as a temporary storage device for 8-bit data, and it can also be employed as a buffering device for bus-oriented systems. The transparent latches allow data to pass from input to output while the latch-enable (LE) input is high, and capture data when LE goes low. The 3-state outputs can be controlled via the output enable (OE) input, allowing for the direct connection to bus lines or other output ports without the risk of a conflict.

This particular variant, the PW package, comes in a TSSOP20 (Thin Shrink Small Outline Package with 20 leads), which is suitable for space-constrained applications due to its compact footprint. The device operates over a wide supply voltage range from 2.0V to 5.5V, which allows for its use in both 3.3V and 5V systems. This flexibility in voltage compatibility is a significant advantage for designers looking to integrate the 74AHC373PW into multi-voltage systems.

Key features of the 74AHC373PW include:

• High-speed, low-power CMOS technology
• Octal D-type transparent latches with 3-state outputs
