Part Number: SN74LVC1G386

Hello,

Regarding to output type on SN74LVC1G386, my customer is asking a question.

(Question)

･According to web page, output type is push-pull,

but according to data sheet page 6 (note E), this device has open-drain outputs.

Which is correct? (push-pull or open-drain?)

Regards,

This device has push/pull outputs.

Figure 1 on page 6 shows the test conditions for measuring t_PZL/t_PLZ/t_PHZ/t_PZH. The "Z" indicates the high-impedance state, which this device does not have (it does not even have an enable pin).

See note H: "All parameters and waveforms are not applicable to all devices." But it appears figure 1 was copy-pasted into this datasheet even though it is not applicable. Forget about figure 1, and look only at figure 2.

Tao,

Yes, the device has pushpull outputs as Clemens rightly suggested (as always :)).
