Hex level translator and line driver works across 1.6 to 5.5V

TI SN74LV6T17-EP hex level translator graph

Texas Instruments has introduced a hex level translator for logic that can also be used as a line-driver. Called SN74LV6T17-EP and part of the LVxT logic family, it contains six independent buffers with Schmitt-trigger inputs. The output level is referenced to the supply voltage, which can span 1.6 to 5.5V and supports 1.8, 2.5, 3.3 and 5V cmos levels. The ...

Scope, logic analyser, waveform generators and more from PC instrument

Digilent Analog Discovery 3

Powered and operated through a USB Type-C cable, Analog Discovery 3 is a 9MHz (or 30MHz) 125Msample/s 14bit oscilloscope, a logic analyser, an arbitrary waveform generator and more from Digilent. “Analog Discovery 2, AD3’s predecessor, has been used as a learning tool in hundreds of universities, and as a flexible benchtop tool by thousands of professional engineering companies and organisations ...

Automotive logic level shifter is automatically bi-directional

Diodes PI4ULS3V304AQ

Diodes has automotive qualified a four-bit bidirectional level translator that does not require a direction control pin. Its B and A ports are designed to track two different power supply rails (VccB and VccA). “Flexibility is maximised because VccA can be set to a value that is independent and either greater than or less than the VccB supply,” according to the company. ...

Mini modules combine driver chip and output mosfets for dc-dc converters up to 100A

Vishay-SIC822-SIC822A-package

Vishay has announced power stages for synchronous buck converters that allow a logic-level PWM signal to control 70, 80 or 100A outputs. There are six parts that will handle inputs from 4.5 – 16V (see table below) then four that will handle 4.5 – 21V – there is no 100A option in the higher voltage devices. Different versions are tuned for 3.3 ...

Re-updated: Handy pulse stream divide-by-n for the lab

EinW-divide-by-n-circuit

Presented with a rotary sensor challenge, I needed a divide-by-13 for a pulse stream. The correct answer was to programme an 8pin ATtiny85 to do the job, but I didn’t want to be distracted by re-climbing the programming learning curve. Circuit (right) updated to avoid potential mis-counts So I had a quick Google for a one-chip answer and came across ...

Improved: isolated wide range zero-crossing detector needs no power switch

improved-zero-crossing-detector-828

A while ago I needed a piece of test gear – an isolated way to transfer zero-crossing information from a variable ac power source: 1Vp-p to 200Vp-p 1Hz to ~1kHz The exact zero crossing point is not important in this application, as long as some point in each cycle is transferred across consistently. And this is what I came up ...

‘Microchip Technology Caldicot’ in Wales works on nano-relay logic project

zeroamp-300x200.jpg

Microchip has changed the name of its UK subsidiary that is working on nano-relay-based logic and memory for an EU ultra-low-power computing and memory project. Caldicot-based Microsemi Semiconductor is now ‘Microchip Technology Caldicot’. “The organisation is the lead partner in the ZeroAMP Project, an industry-driven initiative funded by the Horizon2020 EU Research and Innovation Program that is focused on developing ...

PCIM: 175°C linear reg and logic gates for automotive

Cissiod-CXT-STA4919-app

Cissoid has announced an adjustable linear regulator and logic gates that operate with junction temperature from -55°C up to 175°C – exceeding AEC-Q100 Grade 0 standard, the Belgian high-rel chip maker pointed out. Members of the firm’s new CXT series of automotive grade components, all with the same temperature range, the first is CXT-STA4919, a 50mA adjustable linear voltage regulator that can create ...

Electronica: NXP claims smallest 8pin logic ever

NXP GX8 SOT1233

Aiming at phones and IoT, 8pin logic is now available in 0.8 x 1.35mm packages – the smallest yet claims NXP. The SOT1233 devices, which the firm calls GX 8 packaging, are only 0.35mm high. “The GX 8 leadless package addresses the continual trend in electronic systems towards smaller and smaller packages, low-power consumption and low system costs,” said the firm. ...

Ferrite-Cores And Transistor-Based Logic Here To Stay

‘Commenting upon the apparently universal adoption of ferrite-core storage and transistor-based logic in contemporary computers, the science correspondent of a Sunday newspaper recently concluded that a period of stability in computer technology was now with us.’ So, 52 years ago, starts a story in Electronics Weekly’s edition of May 17 1961.
