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:
– 16-pin 150 mil wide plastic QSOP (Q)

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.
These are high-speed two independent 1-of-4 decoders. Each
decoder accepts two binary weighted inputs (A0, A1) and gives
four mutually exclusive active LOW outputs (O0-O3: PI74FCT139T)
or active HIGH outputs (O0-O3: PI74FCT239T). There is one active
LOW enable (E) for each decoder. For the PI74FCT139T all outputs
are forced HIGH, and for the PI74FCT239T all outputs are forced
LOW when E is HIGH.
