TC74ACT240,244P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT240P, TC74ACT240F, TC74ACT240FT TC74ACT244P, TC74ACT244F, TC74ACT244FT Octal Bus Buffer TC74ACT240P/F/FT TC74ACT244P/F/FT Inverted, 3-State Outputs Non-Inverted, 3-State Outputs TC74ACT240P, TC74ACT244P The TC74ACT240 and 244 are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate and double-layer metal wiring C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The 74ACT240 is an inverting 3-state buffer while the 74ACT244 is non-inverting. Both devices have two active-low output enables. These devices are designed to be used in such applications as 3-state memory address drivers. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features High speed: tpd = 5.0 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 50 Ω transmission lines. Balanced propagation delays: tpLH ∼− tpHL Pin and function compatible with 74F240/244 TC74ACT240F, TC74ACT244F TC74ACT240FT, TC74ACT244FT Weight DIP20-P-300-2.54A SOP20-P-300-1.27A TSSOP20-P-0044-0.65A : 1.30 g (typ.) : 0.22 g (typ.) : 0.08 g (typ.)
