MM74HC688WM Description

Short technical summary and product information.

The MM74HC688WM from On Semiconductor is an 8-bit magnitude comparator designed to compare two 8-bit words bit by bit, indicating equality with an active-low output. This device utilizes advanced silicon-gate CMOS technology and is functionally and pin-compatible with the 74LS688.

 

Key electrical specifications include a wide operating supply voltage range of 2V to 6V. The typical propagation delay is 20ns, with a maximum of 30ns at 6V and 50pF load. It draws a low quiescent current of 8µA typical and can provide a significant output current of up to 5.2mA.

 

This comparator is suitable for applications such as memory block decoding where memory block enable signals are generated from computer address information. The device is housed in a 20-SOIC surface-mount package, facilitating integration into various electronic designs. The operating temperature range is from -40°C to 85°C.

 

All inputs are protected against static discharge damage by diodes to VCC and ground. The active-low enable input allows for cascading multiple packages to compare words greater than 8 bits.
