2Mbit/s (NRZ) opto-coupler with Schmitt trigger

Vishay has introduced a series of 1Mbaud (2MHz NRZ) optocouplers with built-in Schmitt trigger and open collector output. Called the VOH1016A series, the typical input current for output turn-on is 650μA (2mA max required) with guaranteed on-off threshold hysteresis – I(off)/I(on) is between 0.5 and 0.95, typically 0.9 (Vcc 5V, 280Ω load). Output stage supply voltage ...

RRAM-based TCAM ICs can handle large data sets, says Leti.

RRAM-based ternary-content addressable memory (TCAM) circuits can meet the performance and reliability requirements of multicore neuromorphic processors, says Leti.  TCAM circuits provide a way to search large data sets using masks that indicate ranges. These circuits are, therefore, ideal for complex routing and big data applications, where an exact match is rarely necessary. TCAM circuits ...

Six months of over-capacity on 7nm at TSMC

TSMC will have over-capacity on 7nm for the first half of next year, reports the Chinese language newspaper Commercial Times. The reason stated is a cut-back in mobile phone IC orders from HiSilicon, Qualcomm and Apple. The mobile phone industry has plateaued for two years and volumes are expected to decline as phone prices go ...

Imec grows WS2 on 300mm wafers

Imec has  presented a 300mm-wafer platform for MOSFET devices with 2D materials. 2D materials could provide the path towards extreme device-dimension scaling as they are atomically precise and suffer little from short channel effects. Other possible applications of 2D materials could come from using them as switches in the BEOL, which puts an upper limit ...

Devboard and app note open straightforward route to mains EMC filtering

Schurter has released an evaluation board called DKIH-EVB, paired with an application note, which together allows EMC filters to be created and optimised. The user and their spectrum analyser are walked though a six step iterative process that should lead to a cost-effective filter that gets the job done. According to the firm, the universal design allows ...
