Texas Instruments 8-Bit HCT Active Low Inverting Logic Comparator 20-Pin PDIP CD74HCT688E

Texas Instruments CD74HCT688E is an 8-bit high-speed CMOS logic comparator with active low and inverting output functionality housed in a 20-pin PDIP package. It belongs to the 74HCT CMOS logic family, which is designed to provide high speed with low power consumption typical of standard CMOS ICs.

This logic comparator operates within a supply voltage range of 4.5 V to 5.5 V, making it compatible with common digital logic voltage standards. It is specifically engineered to interface TTL inputs with CMOS outputs, ensuring seamless integration in mixed-logic environments.

The device supports a maximum propagation delay time of 29 ns, making it suitable for timing-critical digital circuits. It also delivers output currents up to ±4 mA, sufficient for driving typical logic loads. The operating temperature range from -55°C to 125°C supports rugged and industrial environments.

With a standard 20-pin PDIP through-hole mount package, the CD74HCT688E offers ease of prototyping and flexibility for board assemblies. Its compact dimensions (24.33 mm length, 4.57 mm height) allow use in space-constrained electronic assemblies.

Common applications include identity comparison in digital systems, logic control circuits, signal processing, and various embedded system designs in industrial, commercial, and laboratory electronic equipment contexts.
