6.4.3 High-Drive Outputs

The outputs of this device are capable of driving larger currents than the device can sustain without being damaged. Two outputs can be connected together for 2X stronger output drive strength. The electrical and thermal limits defined in the Absolute Maximum Ratings must be followed at all times.

The maximum frequency of the TXH0137D-Q1 is dependent on the components of the system. The device can operate at speeds up to 100kHz for up translation and < 1MHz for down translation given the correct conditions.

Equation 3. M b p s   d a t a r a t e   =     1 6 × R P U   ×   C

where

  • RPU is the pull-up resistor
  • C is the load capacitance
