SN74AVC4T245DRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC4T245DRG4 is a 4-bit dual-supply noninverting bus transceiver with configurable voltage-level shifting and 3-state outputs. It supports VCCA and VCCB supply voltages ranging from 1.2V to 3.6V, enabling bidirectional translation between nodes such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device achieves maximum data rates of up to 380Mbps during 1.8V to 3.3V translation. It features I/Os that are 4.6V tolerant and includes Ioff circuitry for partial power-down mode operation. The component operates within an ambient temperature range of -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific DRG4 suffix against the manufacturer's latest documentation to confirm package dimensions and tape-and-reel specifications. Ensure input pins are held at valid logic levels to prevent excess current consumption. Confirm that the OE pin is properly biased during power-up sequences to maintain high-impedance states until supplies stabilize.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when asynchronous communication between two data buses operating at different voltage levels is required. The device is suitable for interfacing push-pull drivers where universal low-voltage bidirectional translation is necessary. Consider the 4.6V tolerance feature if interfacing with higher voltage signals on the I/O ports.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature function?

The Ioff circuitry disables the I/O output circuits when the device is in partial-power-down mode, preventing damaging current backflow through the device.

What is the maximum data rate supported?

The maximum data rate is 380Mbps when translating signals from 1.8V to 3.3V.
