2N7001T Dual-Supply Buffered Voltage Signal Converter

Texas Instruments' 2N7001T 1-bit, dual-supply buffered voltage signal converter for partial-power-down applications

Texas Instruments' 2N7001T is a single-bit buffered voltage signal converter that uses two separate configurable power-supply rails to up- or down-translate a unidirectional signal. The device is operational with both V_CCA and V_CCB supplies down to 1.65 V and up to 3.60 V. V_CCA defines the input threshold voltage on the A input. V_CCB defines the output drive voltage on the B output.

This device is fully specified for partial-power-down applications using the I_off current. The I_off protection circuitry ensures that no excessive current is drawn from or to an input, output, or combined I/O that is biased to a specific voltage while the device is powered down.

The V_CC isolation feature ensures that if either V_CCA or V_CCB is less than 100 mV, the output port (B) enters a high-impedance state.
