Specifications
(typical values under recommended operating conditions, unless specified)
Parameter Value Unit
Propagation delay, An to Bn or Bn to An 7 (74HC)
10 (74HCT) 		ns

Notes
  • When DIR is high, An are inputs.
  • When DIR is low, Bn are inputs.
  • When OE is high, An and Bn are in a high-impedance off state.

Note
Data is maintained by an independent source and accuracy is not guaranteed. Check with the manufacturer's datasheet for up-to-date information.
