4-BIT DUAL SUPPLY TRANSLATING TRANSCEIVER;OPEN DRAIN; AUTO DIRECTION SENSING

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
