SN74LVC3G17: I am looking for SN74LVC3G17 with OE pin.

Part Number: SN74LVC3G17
Other Parts Discussed in Thread: SN74LVC2G126, SN74LVC2G125, SN74HCS126, SN74HCS125, SN74LV125AT

Hi Experts,

We are looking for the logic buffer which has the same function of SN74LVC3G17 with OE control.

5V tolerant with 3.3V supply

3 channel

Ioff support ( even when Vcc is off, user can apply the voltage on the output pins(3.3V) )

OE support (when OE is inactive, output is Hi-Z.)

This is the logic to receive three input signals from an external board.

  • Hi,

    Your best bet is an SN74LVC2G125 (active low OE) or a SN74LVC2G126 (active high OE). These will have the exact same spec as the SN74LVC3G17. However, these are only 2 channel devices and you'll need another either LVC1G or LVC2G device.

    If you're looking for only 1 package, you'll want the SN74HCS125 (active low OE) or the SN74HCS126 (active high OE). Both of these devices are 4-channel, however we don't have any 3 channel buffers with 3-State outputs. These devices also do not support I-Off.

    You might also consider the SN74LV125AT: It's another 4-channel device, with a slightly slower datarate capability than the LVC, but other than that it's pretty similar.

    Thanks!
