Product Summary

The TC74VHC573FT is an advanced high speed CMOS octal latch with 3-state output fabricated with silicon gate C2MOS technology. The TC74VHC573FT 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.
