Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: SN74AUC2G34 Hi Support,
Can you please confirm the pinout mapping for the YZP package for the SN74AUC2G34? The YZP is a csp/dsbga package using alpha-numeric annotation and the pinout is just whole-numbered. Please compare the pinout on page…
Other Parts Discussed in Thread: SN74AUC244 , SN74AUC2G34 Hi team,
I saw the thread ( https://e2e.ti.com/support/processors/f/791/p/777653/2879602?tisearch=e2e-sitesearch&keymatch=sn74auc244%2520%2520SD#2879602 ) about the re-driver for SD card application…
Part Number: SN74AUC2G34 I need a clock buffer that will provide switchable 1.2V or 1.8V CMOS output swing. I propose to use the 74AUC2G34 with switchable supply to select the output level. Source clock is 1.8V CMOS and as I understand 2G34 inputs are…
Part Number: SN74AXC4T774 Other Parts Discussed in Thread: SN74AUC34 , SN74AUC2G34 Hi,
I want use a SN74AXC4T774PW to drive many SPI device.
How many device can be drive??
System spec.:
1: level shift 3.3V => 1.2V
2: use the many SPE_CS pin to select…
Hi Steve,
Here is an answer from a previous post about this. W have many datasheets so unfortunately fixing this will take time.
You are correct.
This is a common error in some of our datasheets that we're looking to fix. For logic devices (SN74...) you…
For loads larger than 3 mA, V OH is not guaranteed at all.
There is no stronger logic family at such a low supply voltage. Use multiple outputs of the '245 in parallel, or add a multichannel buffer like the SN74AUC2G34 or SN74AUC125.
The optimal clock buffer for 1.8 V signals would be the SN74AUC2G34. Its inputs accept 3.3 V, and AUC outputs have dynamic drive strength and do not need termination. (Is TC_FPGA_CLK also 1.8 V? If not, use two 1G buffers.)
Part Number: SN74AVC2T45 Other Parts Discussed in Thread: SN74AXC2T45 , , SN74AUC2G34 SN74AXC2T45 could we apply in 80MHz signal operating, 3.3v to 0.8v?
When the voltage of the clock source is 2.5 V or lower, then AUC family devices (e.g., SN74AUC2G34, SN74AUC1G17) would be fastest. At 3.3 V, LVC would be fastest, but it works down to 1.8 V; '541 or '17 or any other buffer (e.g., SN74LVC3G17/34) are…
