Product details

The CD74HC533E is an octal D-type transparent latch with inverting outputs and tri-state output control. It operates on a 2V to 6V supply.

The 13 ns propagation delay from LE to Q sets the bus timing budget. The 7.8 mA source/sink drive per output is typical for HC logic.

That means it is rated for avionics, satellite, missile guidance, and downhole drilling equipment where the ambient can swing past what industrial-grade parts tolerate. The 20-pin plastic DIP (PDIP) package is through-hole — hand-solderable, socket-friendly, and mechanically robust in high-vibration environments if you stake it or conformal-coat it. If your board is reflow-only, you will want the surface-mount sibling (SOIC or SSOP variant) instead.

Frequently asked questions

Can I replace CD74HC533E with CD74HC573E?

The CD74HC573E is the non-inverting sibling of the CD74HC533E. Both are octal transparent latches with tri-state outputs, same pinout, same supply range, same speed grade. The only difference is output polarity: the 533E inverts, the 573E does not. If your downstream logic expects active-high data, the 573E is a direct swap; if it expects inverted data, stay with the 533E.
