SN74CB3Q3345: Is it possible to use 1pin(OE) pin left open

Part Number: SN74CB3Q3345
Other Parts Discussed in Thread: SN74CB3T3245, SN74CB3Q3245

Dear Specialists,

My customer is considering SN74CB3345 instead of SN74CB3245.

They have a question about OE pin.

I would be grateful if you could advise.


We are considering SN74CB3Q3345 as a replacement for SN74CB3T3245.

The SN74CB3T3245 and SN74CB3Q3345 differ in the function of pin1.

Current: SN74CB3T3245DGVR 1pin function: NC
Substitute: SN74CB3Q3345DGVR 1pin Function: OE

When the SN74CB3Q3345DGVR pin 19: OE~ pin is connected to GND, is it possible to use pin 1: OE pin left open?

In addition, 1pin: Is OE terminal internally pulled up or pulled down?

Bus Switch is fixed to ON state.


I appreciate your great help in advance.

Best regards,
