 DESCRIPTION
The UTC UNTS0304 is a 4-bit, dual supply translating transceiver
family with auto direction sensing, that enables bidirectional voltage
level translation. It features eight 1-bit input-output ports (A and B),
one output enable input (OE) and two supply pins (VCCA and VCCB).
VCCA can be supplied at any voltage between 0.95V and 3.6V. VCCB
can be supplied at any voltage between 1.65V and 5.5V. This flexibility
makes the device suitable for translating between any of the voltage
nodes (0.95V, 1.2V, 1.8V, 2.5V, 3.3V and 5.0V). Pins A and OE are
referenced to VCCA and pin B is referenced to VCCB. A LOW level at pin
OE causes the outputs to assume a high-impedance OFF-state.

 FEATURES
* Wide supply voltage range:
VCCA: 0.95V to 3.6V
VCCB: 1.65V to 5.5V
* No power-sequencing required
* Maximum data rate: Open-drain: 2 Mbps; Push-pull: 20 Mbps
* Longer one-shot pulse for driving larger capacitive loads with much
reduced ringing and overshoot
* A-side and OE inputs accept voltages up to 3.6V and are 3.6V
tolerant
* B-side inputs accept voltages up to 5.5V and are 5.5V tolerant
* Package options: TSSOP14 and WLCSP12
* Specified from -40 °C to +125 °C
