Texas Instruments TXH0137D-Q1 Voltage-Level Translator
Texas Instruments TXH0137D-Q1 Voltage-Level Translator is a 7-bit, single-supply, inverting fixed-direction voltage-level translation device. This device has open-drain outputs that support currents up to 100mA per channel and voltages up to 30V. These outputs can be used in parallel for even higher current capabilities. The outputs are more susceptible to large overshoots caused by load reactance at these very high currents. To combat this, the outputs are equipped with clamping overshoot-protection diodes.
The Texas Instruments TXH0137D-Q1 has inputs with improved noise immunity and supports a wide range of input transition rates. The inputs are also overvoltage-tolerant, with integrated static 1MΩ pull-downs.
