The 74VHCT573A is an advanced high speed CMOS OCTAL LATCH with 3-STATE OUTPUT fabricated with silicon gateC2MOS 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. The input voltage are compatible with TTL output voltage. This device may be used as a level converter for interfacing 3.3V to 5 V system. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc.

Wide operating temperature range: Topr = -40 to 125 
High speed: Propagation delay time = 7.7 ns (typ.) at VCC = 5.0 V
Low power dissipation: ICC = 4.0 μA (max) at Ta = 25
Compatible with TTL inputs: VIL = 0.8 V (max)VIH = 2.0 V (min)
Power down protection is provided on all inputs and outputs.
Balanced propagation delays: tPLH ≈ tPHL
Low noise: VOLP = 1.5 V (max)
Pin and function compatible with the 74 series (74ACT/HCT/AHCT etc.) 573 type.
