TC74VHC374FT
TC74VHC374F/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC374F,TC74VHC374FT,TC74VHC374FK Octal D-Type Flip Flop with 3-State Output The TC74VHC374 is an advanced high speed CMOS OCTAL FLIP-FLOP with 3-STATE OUTPUT fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This 8-bit D-type flip-flop is controlled by a clock input (CK) and an output enable input ( OE ). When the OE input is high, the eight outputs are in a high impedance state. An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. TC74VHC374F TC74VHC374FT Features • High speed: fmax = 185 MHz (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC (min) • Power down protection is provided on all inputs. Balanced propagation delays: tpLH ∼ tpHL − • • Wide operating voltage range: VCC (opr) = 2 to 5.5 V • Low noise: VOLP = 0.9 V (max) • TC74VHC374FK Pin and function compatible with 74ALS374 Weight SOP20-P-300-1.27A : 0.22 g (typ.)
