ON Semiconductor MC74HC373AFEL Octal D-Type Latch

The MC74HC373AFEL from ON Semiconductor is a high-performance, octal D-type latch that is designed for use in a wide range of digital applications. This integrated circuit is part of the HC family and offers a robust latch solution with octal D-type flip-flops featuring transparent latches. When 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 set up at the D inputs.

A significant feature of the MC74HC373AFEL is its high noise immunity characteristic of CMOS devices. This makes it an ideal choice for applications that require stable operation in electrically noisy environments. The device operates over a broad voltage range from 2V to 6V and is characterized for operation from -55°C to 125°C, making it suitable for automotive, industrial, and consumer applications where reliability is critical.

The MC74HC373AFEL also includes an additional feature with the 3-state outputs. These outputs are controlled by the output enable (OE) input. When OE is high, the outputs are in a high impedance state, which is particularly useful for interfacing with bus-oriented systems where multiple devices need to share the same output lines.

Constructed with silicon gate CMOS technology, the device assures low power consumption and a balanced propagation delay. This is essential for power-sensitive and timing-critical designs. The MC74HC373AFEL comes in a flat 20-lead package, specifically the SOEIAJ-20 package, which is suitable for surface-mounted technology (SMT) and offers a compact footprint for space-constrained applications.

With its robust design and versatile features, the MC74HC373AFEL is a reliable and efficient solution for designers looking to implement latches in their digital systems. Whether it's used in communication devices, computer peripherals, or control systems, this ON Semiconductor product ensures a high level of performance and integration ease.
