1 / 9 page TC74VHCT240,244AF/AFT/AFK 2008-12-01 1 TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHCT240AF,TC74VHCT240AFT,TC74VHCT240AFK TC74VHCT244AF,TC74VHCT244AFT,TC74VHCT244AFK Octal Bus Buffer TC74VHCT240AF/AFT/AFK Inverted, 3-State Outputs TC74VHCT244AF/AFT/AFK Non-Inverted, 3-State Outputs The TC74VHCT240A and 244A are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The TC74VHCT240A is an inverting 3-state buffer having two active-low output enables. The TC74VHCT244A is a non-inverting 3-state buffer, and has two active-low output enables. These devices are designed to be used with 3-state memory address drivers, etc. The input voltage are compatible with TTL output voltage. These devices may be used as a level converter for interfacing 3.3 V to 5 V system. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc. Note: Output in off-state Features • High speed: tpd = 6.1 ns (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • Compatible with TTL inputs: VIL = 0.8 V (max) VIH = 2.0 V (min) • Power down protection is provided on all inputs and outputs • Balanced propagation delays: tpLH ∼− tpHL • Low noise: VOLP = 1.0 V (max) • Pin and function compatible with the 74 series (74AC/HC/F/ALS/LS etc.) 240/244 type.
