1 / 9 page TC74VHCV240,244FT/FK 2010-07-09 1 TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHCV240FT,TC74VHCV240FK TC74VHCV244FT,TC74VHCV244FK Octal Schmitt Bus Buffer TC74VHCV240FT/FK Inverted, 3-State Outputs TC74VHCV244FT/FK Non-Inverted, 3-State Outputs The TC74VHCV240 and 244 are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate CMOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The 74VHCV240 is an inverting 3-state buffer having two active-low output enables. The TC74VHCV244 is a non-inverting 3-state buffer, and has two active-low output enables. Input pin have hysteresis between the positive-going and negative-going thresholds. Thus the TC74VHCV240 and 244 are capable of squaring up transitions of slowly changing input signals and provides an improved noise immunity. 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, etc. Note: Output in off-state Features • High speed: tpd = 3.9 ns (typ.) at VCC = 5 V • Low power dissipation: ICC = 2 μA (max) at Ta = 25°C • Wide operating voltage range: VCC (opr) = 1.8 V to 5.5 V • Ouput current: |IOH|/IOL = 16 mA (min) (VCC = 4.5 V) • Available in TSSOP and VSSOP (US) • Power-down protection provided on all inputs and outputs • Pin and function compatible with the 74 series (74AC/VHC/HC/F/ALS/LS etc.) 240/244 type TC74VHCV240FT, TC74VHCV244FT TC74VHCV240FK, TC74VHCV244FK Weight TSSOP20-P-0044-0.65A : 0.08 g ( typ.) VSSOP20-P-0030-0.50 : 0.03 g ( typ.) |
