TC74LVX573FT

TC74LVX573F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LVX573F, TC74LVX573FT Octal D-Type Latch with 3-State Output The TC74LVX573F/ FT is a high-speed CMOS octal latch with 3-state output fabricated with silicon gate CMOS technology. Designed for use in 3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. This device is suitable for low-voltage and battery operated systems. This 8 bit D-type latch is controlled by a latch enable input (LE) 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 5.5V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V 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 = 6.4 ns (typ.) (VCC = 3.3 V) Low-power dissipation: ICC = 4 μA (max) (Ta = 25°C) Input voltage level: VIL = 0.8 V (max) (VCC = 3 V) VIH = 2.0 V (min) (VCC = 3 V) Power-down protection provided on all inputs Balanced propagation delays: tpLH ∼− tpHL Low noise: VOLP = 0.8 V (max) Pin and function compatible with 74HC573 TC74LVX573F TC74LVX573FT Weight SOP20-P-300-1.27A TSSOP20-P-0044-0.65A : 0.22 g (typ.) : 0.08 g (typ.)
