74ALVC164245DGG,112 16-bit dual-supply translating transceiver 

The 74ALVC164245DGG,112 is a 16-bit dual-supply translating transceiver with 3-state outputs from Nexperia, designed for high-speed, low-power mixed-voltage interfacing in modern electronic systems. Housed in a 48-pin TSSOP package (TSSOP-48), this device features two independent 8-bit bidirectional transceivers that allow seamless data transfer between voltage domains ranging from 1.5 V to 5.5 V. The transceiver operates with a wide supply voltage range, supporting Port A at 1.5 V to 3.6 V and Port B at 1.5 V to 5.5 V, making it ideal for interfacing between 3.3 V and 5 V logic families. With an operating temperature range of −40 °C to +125 °C, automotive-grade qualification, and RoHS compliance, the 74ALVC164245DGG,112 is well-suited for industrial, automotive, and consumer applications requiring robust voltage translation and bus isolation.

74ALVC164245DGG,112 transceiver Key Features

Key features include dual independent 8-bit bidirectional transceivers with non-inverting 3-state outputs, enabling bidirectional data flow between two buses operating at different voltage levels. The device supports a wide supply voltage range: Port A operates from 1.5 V to 3.6 V, while Port B operates from 1.5 V to 5.5 V, with 5 V tolerant inputs and outputs for direct interfacing to 5 V logic. It offers low power consumption typical of CMOS technology, with a maximum propagation delay of 9.5 ns and a load capacitance of 50 pF, ensuring high-speed operation in data-intensive applications. Additional features include common control inputs for direction and output enable, high-impedance outputs when either supply is off, and ESD protection exceeding 2000 V HBM and 200 V MM, providing robust system-level protection. The device is housed in a 48-pin TSSOP package with a 0.5 mm pitch, featuring gull-wing leads and nickel/palladium/gold (Ni/Pd/Au) terminal finish for reliable surface-mount assembly.
