Quad 2-Input OR Gate
The TC74ACT32 is an advanced high speed CMOS 2-INPUT OR GATE fabricated with silicon gate and double-layer metal wiring C2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar
Schottky TTL 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.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features
High speed: tpd = 4.5 ns (typ.) at VCC = 5 V Low power dissipation: ICC = 4 μA (max) at Ta = 25°C Compatible with TTL outputs: VIL = 0.8 V (max)
VIH = 2.0 V (min) Symmetrical output impedance: |IOH| = IOL = 24 mA (min)
Capability of driving 50 Ω transmission lines. Balanced propagation delays: tpLH ∼− tpHL Pin and function compatible with 74F32
