Description
Introduction to 74AVC4TD245GU,115
- It’s TI’s SN74AVC4TD245: a 4-bit bidirectional bus transceiver with 3-state outputs, used for level shifting and buffering between two voltage domains.
- Structure: A side (A0–A3) and B side (B0–B3); DIR selects A→B or B→A data flow; /OE (output enable) tri-states both sides when deasserted.
- Power: dual-supply operation with independent VCCA and VCCB rails; GND common. Enables interfacing devices at different logic levels.
- Package: suffix GU indicates a specific TI package type; 115 is likely a date/lot code.
- Applications: interconnecting microcontrollers, memory, or peripherals across voltage domains, level shifting, and bus buffering in mixed-signal systems.
- For exact electrical specs (voltage ranges, delays, power), consult the SN74AVC4TD245 datasheet.

Equivalent
Equivalent parts to TI SN74AVC4TD245GU,115 are other 4-bit bidirectional bus transceivers in the 74AVC family from different vendors. Common cross references: Nexperia 74AVC4T245; STMicroelectronics 74AVC4T245 (and other 74AVC4T245-series variants). If exact voltage thresholds allow, 74VHC/74ACT245 family devices can sometimes substitute. Always verify VCCA/VCCB, speed grade, and packaging (GU) before substituting.
Pinout
- Pin count: 14 pins (typical for SN74AVC4TD245-series in GU package).
- Function: 4-bit, dual-supply bidirectional bus transceiver with 3-state outputs. It provides level translation between two sides (A0–A3 and B0–B3). DIR selects the data flow direction (A→B or B→A); OE enables/disables the outputs (active-low). VCCA and VCCB are the two supply rails, plus GND.
