SN74HCS245: 16 channels bus transciever

Part Number: SN74HCS245
Other Parts Discussed in Thread: TXB0108, TXS0108E, SN74CB3Q3245, SN74CB3Q16245

Hi team,

Customer is looking for an 8 or 16 channels bus transciever, the basic requirements includes:

Data rate 250MHz, bi-direction and auto-direction, Enable pin.

I didn't find suitable device from, could you please give some suggestions? Thanks. 



  • There are no auto-direction transceivers because bidirectional signals cannot be buffered. There only auto-direction devices are level shifters (e.g., TXB0108, TXS0108E), and those do not buffer the signals either.

    To disconnect two buses, use a plain switch like the SN74CB3Q3245 or SN74CB3Q16245.

    What is the actual problem you're trying to solve?
