描述 Description

Product Description:
Pericom Semiconductor’s PI74FCT series of logic circuits are produced in the Company’s advanced 0.8 micron CMOS technology, achieving industry leading speed grades.
The PI74FCT521T is an 8-bit identity comparator. When two words of up to eight bits are compared, a bit-for-bit match of the two words provides a LOW output. The comparison can be extended over multiple words by the expansion input. The expansion input IA=B also serves as an active LOW enable input.Product Features:
• PI74FCT521T is pin compatible with bipolar FAST™ Series at a higher speed and lower power consumption
• TTL input and output levels
• Extremely low static power
• Hysteresis on all inputs
• Industrial operating temperature range: –40°C to +85°C
• Packages available:
   – 20-pin 173 mil wide plastic TSSOP (L)
   – 20-pin 300 mil wide plastic DIP (P)
   – 20-pin 150 mil wide plastic QSOP (Q)
   – 20-pin 150 mil wide plastic TQSOP (R)
