The CD74HC688M96 is a high-performance CMOS 8-Bit Identity Comparator manufactured by Texas Instruments. This precision-engineered integrated circuit is designed to offer a reliable solution for digital comparison applications. It is widely utilized in systems where binary data or code needs to be compared for equality, such as in data processing, computing, and control systems.

Key Features

• Logic Type: 8-Bit Identity Comparator
• Supply Voltage Range: 2V to 6V
• Operating Temperature: -55°C to 125°C
• Package / Case: SOIC-20
• Mounting Type: Surface Mount
• Logic Family: HC
• Propagation Delay Time: 13ns at 6V

The CD74HC688M96 is part of the HC family, which is characterized by the high noise immunity and low power consumption of CMOS technology, along with the speed of Schottky TTL devices. Its robust design ensures a wide operating voltage range of 2V to 6V, making it versatile for various applications.

Functional Description

The device consists of eight comparing inputs (A0 to A7) and eight comparing inputs (B0 to B7). An output enable (OE) input and an equality (Q) output are also provided. The Q output indicates the comparison result, which goes low when all pairs of A and B inputs are equal and OE is low. The CD74HC688M96 operates at a propagation delay time of 13ns at a supply voltage of 6V, enabling swift data comparison.

Applications

With its precise comparison capabilities, the CD74HC688M96 is suitable for a variety of applications, including:

• Computer systems for address and data bus matching
• Memory block decoding
• Control systems for error detection
• Input/output port matching
• Peripheral device control

Its small form factor in an SOIC-20 package ensures that it can be easily implemented in space-constrained environments while providing reliable performance in a broad range of operating conditions. The CD74HC688M96 by Texas Instruments stands as a testament to high-quality design and engineering, offering both durability and precision for complex electronic systems.
