MC74LVXC3245DTRG

MC74LVXC3245DTRG is TI’s SN74LVXC series 8‑bit bidirectional bus transceiver with 3‑state outputs. It provides two 4‑bit data paths (A and B) and uses a single DIR input to select transfer direction (A→B or B→A) plus a global OE input to enable/disable both directions. When OE is asserted, data passes between the two sides; when OE is deasserted, the outputs go high‑impedance. It operates from a single low‑voltage supply (typical LV range 1.65–3.6 V), making it suitable for interfacing closely powered buses (e.g., 3.3 V and 2.5 V devices). The device is offered in a 20‑pin package (code DTRG) for surface-mount with tape‑and‑reel delivery. Typical uses include buffering/isolation of microprocessor/memory interfaces, backplanes, and other bidirectional data buses where a compact, low‑power buffer is required. For exact electrical specs and package details, consult the TI datasheet.

Function: MC74LVXC3245DTRG is an octal (8-bit) bidirectional bus transceiver with tri-state outputs. It transfers data between two 8-bit buses (A-side and B-side). The direction is controlled by the DIR input and the outputs are enabled/disabled by the OE (enable) control. It operates in the low-voltage CMOS LVXC family (typically 3.3V domain).

MC74LVXC3245DTRG is an octal bidirectional bus transceiver with 3-state outputs (A and B ports) and DIR and OE controls. It performs voltage-level translation between two domains (commonly 3.3V and 5V) while buffering large-capacitance buses.
Typical applications:
- Interfaces between microprocessors/memories/ASICs/FPGA and peripherals across mixed-voltage domains
- Bus buffering and expansion
- Backplanes or inter-board data transfer
- Isolation of devices from heavy loads while preserving data integrity
