NTBA104 Dual supply translating transceiver auto direction sensing 3-state Rev. 2 22 May 2012 Product data sheet 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 and V ). V CC(A) CC(B) CC(A) can be supplied at any voltage between 1.2 V and 3.6 V and V can be supplied at any CC(B) voltage between 1.65 V and 5.5 V, making the 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 and pins Bn are referenced to V . A HIGH CC(A) CC(B) 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 . The I circuitry disables OFF OFF the output, preventing the damaging backflow current through the device when it is powered down. 2. Features and benefits Wide supply voltage range: V : 1.2 V to 3.6 V and V : 1.65 V to 5.5 V CC(A) CC(B) I circuitry provides partial Power-down mode operation OFF 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 CNTBA104 NXP Semiconductors Dual supply translating transceiver auto direction sensing 3-state 3.
