Overview
The 74ALVC164245DL/S410118, produced by NXP USA Inc., is a high-performance, low-power, low-voltage, Si-gate CMOS device. It is a 16-bit (dual octal) dual supply translating transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. This device is designed to interface between a 3 V and 5 V bus in a mixed 3 V and 5 V supply environment, making it ideal for level-shifting applications.
The device can be used as two 8-bit transceivers or one 16-bit transceiver, providing flexibility in system design. The direction control inputs (1DIR and 2DIR) determine the direction of the data flow, while the output enable inputs (1OE and 2OE) control the high-impedance state of the outputs.

Q & A
- What is the primary function of the 74ALVC164245DL/S410118?
The primary function is to act as a 16-bit dual supply translating transceiver, enabling level translation between 3 V and 5 V buses.
- What are the supply voltage ranges for VCC(A) and VCC(B)?
VCC(A) ranges from 1.5 V to 3.6 V, and VCC(B) ranges from 1.5 V to 5.5 V.
- How does the direction control work?
The direction control inputs (1DIR and 2DIR) determine the direction of data flow. nDIR (active HIGH) enables data from nAn ports to nBn ports, and nDIR (active LOW) enables data from nBn ports to nAn ports.
- What is the purpose of the output enable inputs (1OE and 2OE)?
The output enable inputs (1OE and 2OE) control the high-impedance state of the outputs. When HIGH, they disable both nAn and nBn ports by placing them in a high-impedance OFF-state.
- What are the operating temperature ranges for this device?
The device operates from -40 °C to +125 °C.
- Does the device have ESD protection?
- What package type is the 74ALVC164245DL/S410118 available in?
The device is available in an SSOP48 package.
- Is the device compliant with any industry standards?
- What are some common applications for this device?
- How does the device handle power-down or suspend mode?
