TC74VHC573F/FW/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC573F,TC74VHC573FW,TC74VHC573FT,TC74VHC573FK Octal D-Type Latch with 3-State Output The TC74VHC573 is an advanced high speed CMOS OCTAL LATCH 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 latch is controlled by a latch enable input (LE) and a 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. Features High speed: tpd = 4.5 ns (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 = 1.2 V (max) Pin and function compatible with 74ALS573 Note: xxxFW (JEDEC SOP) is not available in Japan.
