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

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
