Part Number: SN74AUC125 Hello expert,
My customer is asking how long can SN74AUC125 on trace length. Also the loss on SN74AUC125. Could you provide the information for us? Thanks a lot!
Part Number: SN74AUC125 My customers request:
I have to handle two 1.8V-SPI-Interfaces (each with 4 signals: CLK,CS,MOSI,MISO) between two components, which are sometimes partially powered. During “power-save-mode”
In order to fulfill the…
Part Number: SN74AUC125 Hello, Regarding to IBIS model on SN74AUC125,my customer is asking a question.
(Question) The version of current IBIS model is 3.2. Do you have a IBIS model later than v3.2 on this device?
One clock cycle consists of two pulses, high and low, which corresponds to two bits. So 80 MHz = 160 Mbps, which is too fast for this device.
Better use a low-voltage logic family like AUC. For level-shifting to a lower voltage, you can simply use a buffer…
LVC is optimized for 3.3 V. At 1.8 V, it supports only 40 MHz.
You should use AUC family devices, e.g., SN74AUC125 or SN74AUC34, which support 125 MHz. Furthermore, AUC outputs have additional features to improve signal quality.

My customer observed strange behavior with SN74AUC125 as attached. Even though OE…
The datasheet allows this.
But the TXB is too weak to properly buffer signals. For unidirectional signals, you can use a plain buffer like the SN74LVC125A (40 Mbps) or SN74AUC125 (125 Mbps). For unidirectional signals going in both directions, use a direction…
When the output voltage is higher than V CC , a current will flow through the ESD protection diode from the output to V CC .
There are devices with the "partial-power-down (I off )" feature, which allows voltages at the outputs when the device is powered…
