Description

74AVC2T245GUX is a dual-supply, bidirectional bus transceiver with two data channels. It translates signals between two voltage domains: A-side pins powered from VCCA and B-side pins powered from VCCB. A single DIR input selects the direction (A→B or B→A), and a common OE tri-states both sides. It provides two 2-bit (two-channel) paths, enabling fast, hardware-level level shifting without extra resistors or buffers. Typical uses include interfacing microcontrollers, memories, or peripherals across different IO voltages and backplane/databus bridging. Benefits: compact 2-channel level shifter, standard CMOS performance, low power, and easy integration. For exact voltage ranges, timing specs, and packaging details (GUX suffix), refer to the datasheet.

Equivalent

Equivalent parts (dual 2-bit bus transceiver with direction and 3-state outputs) from other vendors:
- MC74AVC2T245 (Onsemi)
- 74AVC2T245 (Nexperia)
Note: packaging and lead-frame variants differ (GUX is TI’s package). Use a distributor cross-reference (Digi-Key/Mouser) to confirm exact package, voltage range, and availability.

Features

Here are the main features of 74AVC2T245GUX:
- Dual 4‑bit bidirectional bus transceivers (8 I/O total)
- Non‑inverting data paths
- 3‑state outputs with individual output‑enable control
- Separate direction control per 4‑bit block (A↔B data direction)
- A‑port and B‑port for flexible two‑way data transfer
- Wide operating voltage: Vcc in 2.5 V–5.5 V range; CMOS/TTL‑compatible input thresholds
- High‑speed CMOS performance with low power consumption
- Ioff (partial‑power‑down) support to prevent back‑powering
- ESD protection and RoHS‑compliant (GUX) packaging
Applications: bidirectional bus buffering and level/reset bridging between different voltage domains.

Pinout

- Pin count: 20 pins (GUX package)
- Function: Dual 2-bit bidirectional bus transceiver/voltage-level translator. Transfers data between A-side (VCCA) and B-side (VCCB) with DIR controlling direction and OE enabling tri‑state outputs. Used for level shifting and buffering between two voltage domains.

Manufacturer

Manufacturer: Nexperia. Nexperia is a Dutch multinational semiconductor company (originally part of Philips/NXP) that designs and manufactures discrete devices, logic ICs, and MOSFETs for automotive, industrial, and consumer electronics applications.

Application

Typical applications of the 74AVC2T245GUX:
- Bidirectional four-bit bus buffering for microcontrollers/FPGA/ASIC data paths
- Level shifting between voltage domains (e.g., 3.3 V and 5 V) with tri-state I/Os
- Bus isolation and buffering on backplanes, motherboards, and connectors
- I/O expansion and rapid prototyping in digital systems
- Interface between processors and memories/peripherals using two independent 4-bit channels
- General high-speed data path buffering where controlled direction and tri-state behavior are needed.

Package

Package: 20-pin TSSOP (Green/RoHS-compliant). The GUX suffix indicates RoHS lead-free packaging.
