- Specification values of the model 244 type (8bit buffer).
- Individual products and LMOS may have different specifications. Give preference to specifications in technical documents of each product.
As for the power supply voltage, TC74VCX/LCX/LVX/VHC series for 3V，TC74VHC/AC/HC series for 5V，TC4000 / 4500 series for 5 to 15V are available.
Types whose input is LVTTL level (VIH/L=2.0 / 0.8V) are available for both 5V and 3V.
