The 74VHC373FT is an advanced high speed CMOS OCTAL LATCH with 3-STATE OUTPUT fabricated with silicon gate C^2MOS 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 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.
Wide operating temperature range: Topr = -40 to 125 °C
High speed: Propagation delay time = 5.0 ns (typ.) at Vcc = 5 V
Low power dissipation: Icc = 4.0µA (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) = 2.0 V to 5.5 V
Low noise: Volp = 0.8 V (max)
Pin and function compatible with the 74 series (74AC/HC/AHC/LV ) 373 type
