1. general description the ntba104 is a 4-bit, dual supply translating transceiver with auto direction sensing, that enables bidirectional voltage level translation. it features two 4-bit input-output ports (an and bn), one output enable input (oe ) and two supply pins (v cc(a) and v cc(b) ). v cc(a) can be supplied at any voltage between 1.2 v and 3.6 v and v cc(b) can be supplied at any voltage between 1.65 v and 5.5 v, making th e device suitable for translating between any of the low voltage nodes (1.2 v, 1.5 v, 1.8 v, 2.5 v, 3.3 v and 5.0 v). pins an and oe are referenced to v cc(a) and pins bn are referenced to v cc(b) . a high level at pin oe causes the outputs to assume a high -impedance off-state. this device is fully specified for partial power-down applications using i off . the i off circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. 2. features and benefits ? wide supply voltage range: ? v cc(a) : 1.2 v to 3.6 v and v cc(b) : 1.65 v to 5.5 v ? i off circuitry provides partial power-down mode operation ? inputs accept voltages up to 5.5 v ? esd protection: ? hbm jesd22-a114e class 2 exceeds 2500 v for a port ? hbm jesd22-a114e class 3b exceeds 15000 v for b port ? mm jesd22-a115-a exceeds 200 v ? cdm jesd22-c101e exceeds 1500 v ? latch-up performance exceeds 100 ma per jesd 78b class ii ? multiple package options ? specified from ? 40 ? cto+85 ? c and ? 40 ? cto+125 ? c ntba104 dual supply translating trans ceiver; auto dire ction sensing; 3-state rev. 1 ? 6 december 2011 product data sheet
