One-Gate Logic with Single Power Supply

Toshiba announced the release of the new 31 single power supply one-gate logic device series 7UL1G’ and ‘7UL1T.  Both series devices support low-voltage operation and implement voltage-level translation with a single power supply allowing easier design of voltage-level translation circuits with no concerns about the power-on-sequence or voltage restrictions between the two power supplies unlike its previous products.

 

The new ‘7UL1G series’ offers down-translation to 0.9V and ‘7UL1T series’ offers up-translation from 1.8V-3.3V. The voltage-level design used for data communication control will be made easy on devices with multiple power supplies. The 7UL1G series devices operate with 0.9V to 3.6V power supply and the terminals can tolerate up to 3.6V. The 7UL1T series devices will operate with a power supply of 2.3V to 3.6V and the input threshold voltage is set to 50% or less of the power supply voltage. This will make it a perfect fit in application areas such as Data communication control circuits of devices with multiple power supply systems, smartphones, tablets, laptop PCs, POS and IoT equipment.

 

The features include:

1. Voltage-level translation with a single power supply for low voltage systems:

  • Up-translation from 1.65V input to 3.6V output(7UL1T series)

  • Down translation from 3.6V input to 0.9V output[4] (7UL1G series)

2. Built-in power down protection function

 

Specifications:

  • Input Voltage Vin= 0 to 3.6V

  • Output Current IOH, IOL =  +8.0 and -8.0

  • Operating Temperature Topr =  -40 to 850C

  • Power-OFF Current IOFF Max  = 1.0 uA

  • Quiescent Supply current ICC MAX = 1.0 uA

 

All the devices will be available in the industries smallest lead-type fSV package {Package code: SOT953, 1.0×1.0×0.48 mm (typ.)] and General-purpose USV package [Package code: SOT-353, 2.0×2.1×0.9 mm (typ.)]. The samples are out now and can be ordered from Toshiba website and online distributors.
