The Nexperia 74AVC2T45DP is a 2-bit, dual-supply bidirectional voltage-level translator/transceiver with 3-state outputs. It features two A-side and B-side data channels together with a DIR control input. A HIGH level on DIR transfers data from A to B, while a LOW level transfers data from B to A. Nexperia currently lists the exact 74AVC2T45DP as Production.
Both VCC(A) and VCC(B) operate from 0.8V to 3.6V, allowing translation between common low-voltage logic nodes including 0.8V, 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. This makes the device suitable for interfacing MCUs, processors, FPGAs, memory devices, and peripherals operating from different supply domains.
Maximum data rate reaches 500Mbit/s for 1.8V-to-3.3V translation. Nexperia specifies up to 320Mbit/s when translating from below 1.8V to 3.3V, up to 320Mbit/s when translating to 2.5V or 1.8V, 280Mbit/s when translating to 1.5V, and 240Mbit/s when translating to 1.2V.
Integrated I_OFF circuitry supports partial power-down operation by preventing damaging backflow current when a supply domain is powered off. Suspend mode places both A and B ports in a high-impedance state when either supply is at ground. The device also provides HBM ESD protection above 8kV, CDM protection above 1kV, and latch-up performance exceeding 100mA.
The exact 74AVC2T45DP uses an 8-pin TSSOP / SOT505-2 package with 0.65mm lead pitch and an approximately 3 × 3 × 1.1mm body. The family is specified for temperature ranges extending to -40°C to +125°C.
