• SN74BCT25244: Driving 74BCT25244 BiCMOS octal buffer with 74LS?

  Answer Suggested

  Part Number: SN74BCT25244 Can all 8 channels of this buffer be driven in parallel with the output from a 74LS part? In this particular case a 74LS221 one shot will be used to create a 15mS pulse at 10Hz that needs to be distributed to several other devices…

• SN74BCT25244: Is it OK to ground low-active inputs, or is a pulldown needed?

  TI Thinks Resolved

  Part Number: SN74BCT25244 I want the chip enables always active. Is it OK to tie those pins directly to ground, or do I need to use a pulldown resistor? I've never used BCT parts before and I cannot find any drawings that show the input structure.
