What are the key features of 74AVCA164245GR?
- 16-bit dual-bus architecture with non-inverting CMOS logic enables simultaneous bidirectional data transfer on two independent 8-bit ports
- Wide voltage translation range from 1.2V to 3.6V per port supports mixed-voltage PCB designs bridging 1.8V, 2.5V, and 3.3V logic families
- 48-pin TSSOP package with 1.5ns typical propagation delay minimizes board space and signal latency in high-density bus applications
What is 74AVCA164245GR used for?
The 74AVCA164245GR is used in microprocessor and FPGA designs requiring level translation between 1.8V core logic and 3.3V peripheral buses across 16 data lines simultaneously. Its dual-port architecture supports address/data bus multiplexing in embedded systems and industrial controllers. The AVCA family's low propagation delay of approximately 1.5ns makes it suitable for high-speed memory interface and backplane bus applications.

Frequently Asked Questions
What voltage translation capability does the 74AVCA164245GR provide for mixed-voltage board designs?
The 74AVCA164245GR supports voltage translation across a range of approximately 1.2V to 3.6V on each port independently, enabling bidirectional level shifting between 1.8V and 3.3V logic domains. This is critical in modern SoC designs where the processor core operates at 1.8V but communicates with legacy 3.3V peripherals across 16-bit data and address buses.
How does the 74AVCA164245GR's dual 8-bit structure differ from a single 16-bit transceiver in a PCB layout?
The 74AVCA164245GR implements two independent 8-bit ports each with its own output-enable and direction control, giving designers flexibility to route A-side and B-side signals separately across a 48-pin TSSOP footprint. This contrasts with a monolithic 16-bit transceiver that shares a single OE and DIR control pair, allowing the dual structure to support split-bus or half-bus enable scenarios for lower power states.
In an FPGA prototype board, when is 74AVCA164245GR preferred over SN74LVC16245A for memory bus interfacing?
SN74LVC16245A is limited to 3.3V operation on both ports, making it unsuitable when the FPGA I/O banks run at 1.8V or 2.5V. The 74AVCA164245GR supports mixed-voltage translation down to 1.2V per port with approximately 1.5ns propagation delay, which is critical for DDR2 or LPDDR memory interfaces where the controller outputs 1.8V signals that must be translated for 3.3V legacy connectors without exceeding 3ns maximum setup time.
How many pins does the 74AVCA164245GR have and what does the TSSOP package imply for hand-soldering on a prototype?
The 74AVCA164245GR comes in a 48-pin TSSOP package with 0.5mm pin pitch, which is fine enough to require careful stencil printing or hot-air rework techniques for prototype hand-assembly. Unlike QFN or BGA packages, the TSSOP has visible gull-wing leads enabling visual inspection, though the 0.5mm pitch still requires a fine-tip soldering iron and flux application to avoid bridging between adjacent pins.
