TC74HCT240AF

TC74HCT240,244AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HCT240AP, TC74HCT240AF TC74HCT244AP, TC74HCT244AF Octal Bus Buffer with TTL Input Level TC74HCT240AP/AF Inverted, 3-State Outputs TC74HCT244AP/AF Non-Inverted, 3-State Outputs TC74HCT240AP, TC74HCT244AP The TC74HCT240A, and HCT244A are high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Their inputs are compatible with TTL, NMOS, and CMOS output voltage levels. The TC74HCT240A is an inverting 3-state buffer having two active-low output enables. The TC74HCT244A is non-inverting 3-state buffer the HCT244A has two active-low output enables. These devices are designed to be used with 3-state memory address drivers, etc. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features High speed: tpd = 13 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) Wide interfacing ability: LSTTL, NMOS, CMOS Output drive capability: 15 LSTTL loads Symmetrical output impedance: |IOH| = IOL = 6 mA (min) Balanced propagation delays: tpLH ∼− tpHL Wide operating voltage range: VCC (opr) = 2 to 6 V Pin and function compatible with 74LS240/244 TC74HCT240AF, TC74HCT244AF Weight DIP20-P-300-2.54A SOP20...
