74AVC2T245 2-bit dual supply translating transceiver with configurable voltage translation 3-state Rev. 2 6 April 2017 Product data sheet 1 General description The 74AVC2T245 is a 2-bit, dual supply transceiver that enables bidirectional level translation. The device can be used as two 1-bit transceivers or as a 2-bit transceiver. It features two 2-bit input-output ports (An and Bn) and direction control inputs (DIRn), an output enable input (OE) and dual supply pins (V and V ). Both V and CC(A) CC(B) CC(A) V can be supplied at any voltage between 0.8 V and 3.6 V making the device CC(B) suitable for translating between any of the low voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins An, OE and DIRn are referenced to V and pins Bn are CC(A) referenced to V . A HIGH on DIRn allows transmission from An to Bn and a LOW on CC(B) DIRn allows transmission from Bn to An. The output enable input (OE) can be used to disable the outputs so the buses are effectively isolated. The device is fully specified for partial power-down applications using I . The I OFF OFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down. In suspend mode when either V or V are at CC(A) CC(B) GND level, both An and Bn are in the high-impedance OFF-state. 2 Features and benefits Wide supply voltage range: V : 0.8 V to 3.6 V CC(A) V : 0.8 V to 3.6 V CC(B) Complies with JEDEC standards: JESD8-12 (0.8 V to 1.3 V) JESD8-11 (0.9 V to 1.65 V) JESD8-7 (1.2 V to 1.95 V) JESD8-5 (1.8 V to 2.7 V) JESD8-B (2.7 V to 3.6 V) ESD protection: HBM JESD22-A114E Class 3B exceeds 8000 V CDM JESD22-C101C exceeds 1000 V Maximum data rates: 380 Mbit/s ( 1.8 V to 3.3 V translation) 200 Mbit/s ( 1.1 V to 3.3 V translation) 200 Mbit/s ( 1.1 V to 2.5 V translation) 200 Mbit/s ( 1.1 V to 1.8 V translation) 150 Mbit/s ( 1.1 V to 1.5 V translation) 100 Mbit/s ( 1.1 V to 1.2 V translation) Suspend mode Latch-up performance exceeds 100 mA per JESD 78 Class II Inputs accept voltages up to 3.6 VNexperia 74AVC2T245 2-bit dual supply translating transceiver with configurable voltage translation 3-state I circuitry provides partial Power-down mode operation OFF Specified from -40 C to +85 C and -40 C to +125 C 3 Ordering information Table 1.
