Part Number: TXS4555 Other Parts Discussed in Thread: SN74AXC2T45 Hi Sir,
In customer application, LTE 4G module SIM trace is long to 10000mil(254mm), the max requirement is 150mm, do you think if I add one TXS4555 is workable?
Thank you.

Part Number: TXS4555 Hi,
From Customer, LTE SIM card can negotiate with the host and choosing a right votlage level.
Dose TXS4555 support this kind dynamic vtolage detection and adjustment? or other bidirction level shift can achieve this kind feature…
Hi David,
Welcome to e2e.
Is this a generic voltage translation application?
What are the voltage levels on the MCU and the peripheral?
TXS4555 is a application specific device used for SIM card connectivity.
There are other voltage translation…
Part Number: TXS4555 Hi team,
It is described in TXS4555 datasheet that it can support the power sequence based on ISO7816-3 specification.
I would like to know which test equipment used to confirm this feature.
Could you give me the test report…
Part Number: TXS4555 Hi Sirs,
Sorry to bother you,
Because there have a CPLD controller before baseband and sim,
So our application are
Baseband (3v/1.8) to TS4555 (to 1.8V) to CPLD(1.8V) to TS4555( to 1.8V/3V) to SIM card
Could you help check…
Part Number: TXS4555 Hi Team,
I proposed TXS4555 to customer to connect SIM caed , but TXS4555 need RESET/CLK/IO as input.
may i know what's interface should between CPU and TXS4555?
Customer CPU only had I2C/SPI/GPIO.
Please help to check…
Part Number: TXS4555 Does the TXS4555 require pull-up/pull-down resistors or are they integrated? The EVM doesn't show any pull-up/pull-downs but the data sheet references them in the electrical table on the top of page 7:
R I/OPU I/O pull-up 16 20…
