概要

Description

MC74LVXC3245DTRG is a dual 4-bit, bidirectional bus transceiver with 3-state outputs from the LVXC CMOS family. It is designed to connect two buses that may run at different voltage levels and optionally translate between them.
Key points:
- Two 4-bit data paths (A0–A3 and B0–B3) with a common DIR control to select data flow A→B or B→A.
- OE (output enable) to place outputs in high-impedance when not driving.
- Level shifting between two supplies: VCCA and VCCB, enabling interfacing of different voltage logic families.
- Low-voltage CMOS operation: typically 1.65 V to 3.6 V (suitable for 3.3-V systems).
- Applications include buffering, bus isolation, and voltage-level bridging between microcontrollers, memories, and peripheral devices.
- DTRG denotes RoHS-compliant, tape-and-reel packaging.
If you need exact pinout, timing, or electrical characteristics, consult the TI datasheet for MC74LVXC3245DTRG.

Features

Here are the key features of MC74LVXC3245DTRG:
- 8-bit bidirectional bus transceiver with 3-state outputs (A0–A7 and B0–B7).
- DIR input to select data flow direction (A↔B).
- OE (output enable) to place outputs in high-impedance state.
- Built-in level shifting between two voltage domains (A and B sides) for mixed-voltage systems.
- Low-voltage CMOS operation (typical Vcc range around 1.65V–3.6V, per LVXC family).
- Ioff support (no back-powering when Vcc is 0/partial-power-down scenarios).
- Suitable for high-speed buffering and bidirectional data paths; low static/switching power.
- ESD protection and general-purpose, Pb-free (DTRG) packaging.
Note: Exact Vcc range, drive strength, and timing specs are device- and package-specific—refer to the datasheet for precise numbers.

Package

The MC74LVXC3245DTRG is in a 20‑pin TSSOP (Thin Shrink Small Outline) package, Pb‑free, Tape‑and‑Reel.

Pinout

- Pin count: 20 pins (SOIC-20/TSSOP-20 style).
- Function: Octal bidirectional bus transceiver with 3-state outputs. It provides two 8-bit data buses (A0–A7 and B0–B7); a DIR input selects the direction (A→B or B→A), and an OE input enables/disables the outputs (tri-state when disabled).

Manufacturer

Manufacturer: ON Semiconductor (formerly Motorola).
Company type: A multinational semiconductor company that designs, manufactures, and sells integrated circuits and semiconductor solutions (logic, analog, power management, sensors), headquartered in Phoenix, Arizona, USA.

Application

MC74LVXC3245DTRG is a dual 4‑bit bidirectional bus transceiver with 3‑state outputs and voltage translation. Applications include:
- Level shifting between two voltage domains (e.g., 1.65–3.3 V and 3.3–5 V)
- Bidirectional data buffering/sharing on microprocessor/memory buses
- I/O isolation in mixed-voltage systems, backplanes, and portable devices
- General-purpose 4‑bit bus paths in high/low-speed digital interfaces
