SINGLE-BIT DUAL-SUPPLY BUFFERED VOLTAGE SIGNAL CONVERTER

DESCRIPTION

The UTC 2N7001 is a single-bit buffered voltage signal converter

that uses two separate configurable powersupply rails to up or

down translate a unidirectional signal. The device is operational

with both VCCA and VCCB supplies down to 1.65 V and up to 3.60 V.

VCCA defines the input threshold voltage on the A input. VCCB

defines the output drive voltage on the B output.

This device is fully specified for partial-power-down applications

using the Ioff current. The Ioff 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 VCC isolation feature ensures that if either VCCA or VCCB is

less than 100 mV, the output port (B) enters a high-impedance

state.

FEATURES

* Up and down translation across 1.65V to 3.6V

* Maximum quiescent current (ICCA + ICCB) of 14µA (125°C maximum)

* VCC isolation feature If either VCC input is below 100 mV, the output becomes high-impedance

* IOFF supports partial-power-down mode operation
