Description

The 74AVC2T245GU-Q100X is TI’s dual 4‑bit, bidirectional bus transceiver with tri‑state outputs in the 74AVC family. It buffers and translates data between two voltage domains (A and B). A single DIR input selects the data flow direction (A→B or B→A), and a common OE disables both directions when high‑impedance is needed. The device contains two 4‑bit buses that can operate from different VCCA/VCCB supplies and includes Ioff for partial‑power‑down protection. It’s designed for high‑speed, low‑power operation and is suitable for interfacing microcontrollers, ASICs, and peripherals across mixed‑voltage systems, bus sharing, or back‑planes. The GU suffix denotes package type; Q100X refers to the specific packaging/qualification variant. For exact voltage ranges, timing, and pinout, consult the TI datasheet.

Equivalent

Equivalents depend on voltage, package, and automotive grade. To give exact cross-references, please specify:
- Target voltage range (e.g., 1.65–3.6 V, 5 V tolerant)
- Package (MSOP8, SOIC8, etc.)
- Temperature grade (AEC-Q100, Q100X)
In general, closest alternatives are other vendors’ dual 2-bit bus transceivers with 3-state outputs and the same pinout, but exact compatibility must be confirmed.

Features

Concise features of 74AVC2T245GU-Q100X:
- Dual 2-bit bidirectional bus transceiver with 3-state outputs
- Separate supply rails on each side (VCCA and VCCB) for level shifting between domains
- Direction control (DIR) and output enable (OE) for whole device
- Ioff (partial-power-down) support to prevent back-powering when VCCA/VCCB are 0
- TTL/CMOS-compatible inputs; fast, low-power CMOS technology
- Automotive-grade, AEC-Q100 qualified (Q100X) with extended temperature range (-40°C to 125°C)
- ESD protection and robust I/O protection suitable for mixed-signal buses
- 16-pin package (e.g., small-outline/lead-frame variety) suitable for dense layouts
Note: Exact voltage ranges and timing parameters are specified in the datasheet; this summary emphasizes the key capabilities and usage.

Pinout

- Pin count: 20 pins (20-pin package)
- Function: Dual 2-bit bidirectional bus transceiver with 3-state outputs; transfers data between A-side (A0–A1) and B-side (B0–B1) with independent supplies (VCCA and VCCB), controlled by DIR and OE for tri-state operation.

Manufacturer

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor company that designs and manufactures discrete components and standard logic/analog ICs (including 74xx-like devices), as well as ESD protection and other protection/analog solutions.
