What are the key features of 74AVC8T245DGVRG4?
- 8-bit bidirectional level translation between VCCA (1.65 V–3.6 V) and VCCB (1.65 V–3.6 V) with output enable for tri-state bus control
- AVC family propagation delay below 2 ns at 3.3 V enables high-speed data bus translation in processors, FPGAs, and memory interfaces
- 24-pin TVSOP package with independent VCCA and VCCB rails allows isolation of two different logic domains on a single compact IC
What is 74AVC8T245DGVRG4 used for?
The 74AVC8T245DGVRG4 is used in mixed-voltage embedded systems where 8-bit parallel data buses must be translated between 1.8 V, 2.5 V, and 3.3 V logic domains on microcontrollers, FPGAs, and memory devices. Its bidirectional flow and output enable make it well-suited for microprocessor data buses, SPI expansion, and GPIO level shifting in industrial control and communications equipment. The device is also commonly deployed in PCIe development boards and SoC prototyping kits to bridge between different logic-family peripherals.

Frequently Asked Questions
What supply voltage combinations does the 74AVC8T245DGVRG4 support for level translation between different logic families?
The 74AVC8T245DGVRG4 supports independent VCCA and VCCB supply voltages each ranging from 1.65 V to 3.6 V, allowing translation between 1.8 V and 3.3 V logic, 2.5 V and 1.8 V logic, or any combination within this range. This makes it suitable for interfacing 3.3 V microcontrollers with 1.8 V LPDDR memory or 1.8 V FPGA I/O banks.
How does the AVC logic family propagation speed of the 74AVC8T245DGVRG4 compare to standard LVC or LVTTL translators?
The 74AVC8T245DGVRG4 achieves a typical propagation delay of under 2 ns at 3.3 V, roughly 2x faster than standard LVC family translators which typically show 3 ns to 5 ns delays. This performance advantage makes AVC the preferred choice for high-speed 8-bit bus interfaces operating at 100 MHz and above, such as parallel address buses and SRAM data lines in high-throughput embedded systems.
How should the output enable pin of the 74AVC8T245DGVRG4 be used in a shared bus design?
The 74AVC8T245DGVRG4 provides an active-low output enable (OE) pin that tri-states all 8 outputs when deasserted high, allowing multiple 8-bit transceivers to share the same bus without signal contention. In a multi-device bus, each transceiver's OE should be controlled by the host MCU or FPGA GPIO, ensuring only one device drives the bus at any given time. The DIR pin independently controls translation direction for each enabled transceiver.
