SN74HC684N Description

Short technical summary and product information.

The SN74HC684N from Texas Instruments is an 8-bit magnitude comparator. This integrated circuit is capable of performing comparisons between two 8-bit binary or BCD words, providing (P = Q) and (P > Q) outputs.

 

Key electrical specifications include a wide operating voltage range from 2V to 6V and a maximum propagation delay of 47ns at 6V with a 50pF load. The device operates within a temperature range of -40°C to 85°C.

 

Packaged in a 20-pin PDIP (Plastic Dual In-line Package), the SN74HC684N is designed for through-hole mounting. Its features include high-current outputs capable of driving up to 10 LSTTL loads and low power consumption.

 

This comparator is suitable for applications requiring the comparison of two 8-bit data words.
