Product Summary
The tc74hct32af(f) is a high speed CMOS 2-INPUT OR GATE fabricated with silicon gate C2MOS technology. The tc74hct32af(f) achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels. The tc74hct32af(f) is composed of 4 stages including buffer output, which provide high noise immunity and stable output. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
