Product Overview: 74HC373BQ,115 from NXP Semiconductors

The 74HC373BQ,115 is a high-speed Si-gate CMOS device from NXP Semiconductors, renowned for its exceptional quality and performance in a wide range of electronic applications. This octal D-type transparent latch is part of the 74HC/HCT family, which is known for its compatibility with output input levels of 5V CMOS and TTL logic. It is designed to be used in applications where the capture of the data is necessary for a moment in time, ensuring that the output remains stable while the data is being processed elsewhere in the system.

This particular model, the 74HC373BQ,115, comes in a DHVQFN20 package, which is a leadless, space-saving, and extremely thin quad flat package. The 20-pin package offers a compact footprint for designs where space is at a premium. The device features eight latches with 3-state outputs for bus-oriented applications. The 3-state outputs can be used to interface with and drive the bus lines in a bidirectional manner without the need for external pull-up resistors.

Each latch has a separate D input and O output. The common transparent latch enable (LE) input activates the latches, and when LE 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 just before the HIGH-to-LOW transition of LE. A separate output enable (OE) input is provided for each latch. When OE is LOW, the outputs are on and can drive the bus lines. When OE is HIGH, the outputs are in the high-impedance OFF-state, which is ideal for bus-oriented applications.

With its wide operating voltage range of 2 V to 6 V and its low input current of 1 µA, the 74HC373BQ,115 is suitable for interfacing with TTL levels. It also boasts a high noise immunity and a balanced propagation delay and transition times, making it a robust choice for high-speed digital systems. In summary, the 74HC373BQ,115 from NXP is a versatile and reliable component for any digital logic system requiring transparent latches with 3-state outputs.
