Issue background: 1.8v -3.3v translation RGMII buffer which works well at 100Mbps but fail at the 1000Mbps wi th part SN74AVC8T245 . Now we are question…
Part Number: SN74AXCH8T245 Hi Team
my customer is using SN74AXCH8T245RHLR, VCCA = 1.8V, VCCB = 3.6V, I saw your publications Glitch free power sequencing with AXC level translators (Rev. A) (ti.com) ,
1) As the power-up hi-Z circuit is before the…
Part Number: SN74AXCH8T245SN74AXCH8T245PWR is out of stock, and replace it with SN74LVH8T245PWR. The maximum working temperature of SN74AXCH8T245PWR is 125℃, but the maximum working temperature is 85℃. The board temperature of customer is 90℃. If over…
Part Number: SN74AXCH8T245 Other Parts Discussed in Thread: SN74AXC8T245 , SN74AVC8T245 Hello,
Our customer is experiencing the RGMII issue when using SN74AXCH8T245 as level shifter from 1,8V FPGA to 3.3V PHY (for both TX_CLK and all TX_DATA). Specifically…
Part Number: SN74AXCH8T245 Hi,
I've been reading through data sheets for level translators and some quantify the speed in Mbps and some use MHz. Does Texas Instruments have a standard way of translating between the two? I am not able to find a consistent…

Part Number: SN74AXCH8T245 Hi Team,
My customer found that SN74AXCH8T245PWR propagation delay on datasheet has a MIN and MAX data, but we don`t know why this parameter had MIN/MAX data, is difference between different device? or different data from…
Hi Nir,
OE can be directly tied to gnd pin if the device needs to be always enabled. Tying it to Vcca is optional, and recommended only if the IO ports needs to be in hi-Z before the supply pins are stable.
This is true for both AXCH and AVCH devices…
