The inputs are compatiblewith TTL, NMOS and CMOS output voltage levels.The TC74ACT540 is an inverting type, and the TC74ACT541 isa non-inverting type.When either1G or2Gare high, the terminal outputs are inthe high-impedance state.All inputs are equipped with protection circuits against staticdischarge or transient excess voltage.Features• High speed: tpd = 4.3 ns (typ.) at VCC = 5 V• Low power dissipation: ICC = 8 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 50Ω transmission lines.• Balanced propagation delays: tpLH ∼− tpHL• Pin and function compatible with 74F540/541TC74ACT540P, TC74ACT541PTC74ACT540F, TC74ACT541FTC74ACT540FT, TC74ACT541FTWeightDIP20-P-300-2.54A: 1.30 g (typ.)SOP20-P-300-1.27A: 0.22 g (typ.)TSSOP20-P-0044-0.65A: 0.08 g (typ.)
