DUAL SUPPLY TRANSLATING RANSCEIVER; AUTO DIRECTION SENSING; 3-STATE
DESCRIPTION
The UNTB0102 is a 2-bit, dual supply translating transceiver with auto direction sensing, that enables bidirectional voltage level translation. It features two 2-bit input-output ports (An and Bn), one output enable input (OE) and two supply pins (VCCA and VCCB). VCCA can be supplied at any voltage between 1.2V and 3.6V and VCCB can be supplied at any voltage between 1.65V and 5.5V, making the device suitable for translating between any of the low voltage nodes (1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5.0V).
Pins An and OE are referenced to VCCA and pins Bn are referenced to VCCB. A LOW level at pin OE causes the outputs to assume a high-impedance OFF-state.
