Octal D-Type Latch with 3-State Output

The TC74AC573 is an advanced high speed CMOS OCTAL LATCH fabricated with silicon gate and double-layer metal wiring C2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
These 8-bit D-type latches are controlled by a latch enable input (LE) and a output enable input ( OE ).
When the OE input is high, the eight outputs are in a high impedance state.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
