The 74HCT688N,652 is a high-speed Si-gate CMOS 8-bit magnitude comparator manufactured by NXP Semiconductors. This device is designed to compare two 8-bit binary or BCD words, providing an output indicating equality (P = Q). It is pin compatible with low power Schottky TTL (LSTTL) and specified in compliance with JEDEC standard no. 7A.
Key electrical characteristics include an operating voltage range of 4.5V to 5.5V and a typical operating current of 8 µA. The maximum propagation delay is 34ns at 4.5V with a 50pF load. The output capability is standard, and the output type is active low.
This comparator is housed in a 20-DIP (0.300", 7.62mm) package, suitable for through-hole mounting. The operating temperature range is from -40°C to 125°C. The datasheet also specifies typical values for input capacitance at 3.5pF and power dissipation capacitance at 30pF.
Additional specifications from the datasheet include typical propagation delays of 7ns for Pn, Qn to P=Q and 8-12ns for E to P=Q, both measured at VCC = 5V and CL = 15pF.
