概述

Description

SN74LVCR2245APW is TI’s low‑voltage bidirectional buffer/line driver in the SN74LVCR family. It provides multiple tri‑state buffers arranged as bidirectional bus transceivers with a direction control (DIR) and a global output enable (OE). The device is designed to buffer data between devices on a shared bus (e.g., microprocessors, memory, peripherals), isolating loads and allowing controlled data flow in either direction.
Key points:
- Low‑voltage operation (LV family; typically 1.65V–3.6V)
- Bidirectional data transfer with DIR and OE control
- Tri‑state outputs suitable for bus interfacing
- Available in PW/APW package variants (TI’s package codes)
Typical uses include buffering high‑density data/address buses, or protecting and isolating digital buses between devices in a system.
Note: exact bit width, drive strength, input/output characteristics, and voltage ranges vary by variant. For precise specifications, pinout, and timing, consult the TI SN74LVCR2245APW datasheet.

Features

Here are typical features of the SN74LVCR2245APW:
- 20-bit bidirectional bus transceiver with 3-state outputs
- Two ports labeled A and B for bidirectional data flow
- Direction control input (DIR): selects A→B or B→A data direction
- Output-enable input (OE): disables outputs to high-impedance state
- 3-state outputs on both sides for bus sharing
- Bus-hold on data inputs to prevent floating when not driven
- Low-voltage CMOS-compatible operation (typical LV range) with TTL/CMOS input thresholds
- ESD protection and robust operation per TI standards
- Available in PW package (surface-mount)
Applications include interfacing between different voltage domains, microcontroller-to-memory buses, and other shared-bus systems. For exact supply voltage range, speed, and packaging options, consult the datasheet.

Package

20-pin TSSOP package (PW).

Pinout

Pin count: 20 pins (TSSOP-20 package, PW).
Function: Dual 4-bit bidirectional bus transceiver with 3-state outputs (8-bit total). Allows data transfer between two 4-bit buses; direction controlled by a DIR input and output enable controlled by OE (one enable for the transceiver). Suitable for buffering/interfacing between different bus voltages in low-voltage logic.

Manufacturer

Manufacturer: Texas Instruments (TI).
Company type: American multinational semiconductor company that designs and manufactures a broad range of integrated circuits, analog and digital products, sensors, and related components. It is one of the world’s largest semiconductor makers, headquartered in Dallas, Texas.

Application

SN74LVCR2245APW is a 20-bit, dual 10-bit buffer/driver with tri-state outputs. Typical applications:
- Level shifting and buffering of wide data/address buses between logic families (e.g., 1.8–3.3 V to 5 V)
- I/O expansion and backplane/bus interconnections between microprocessors/FPGA and memories or peripherals
- High-speed, low-power bus routing in portable/consumer electronics
- Bus isolation/sharing and power-down bus control for bus-enabled systems

Equivalent

To give accurate equivalents, please specify target packaging and vendors. SN74LVCR2245APW is TI’s low-voltage octal buffer/driver (3-state). Do you want cross-references for PW/TSSOP-20 only, or also other packages and vendors (e.g., NXP, ON Semiconductor, Renesas, etc.)? If yes, I’ll list exact part numbers.
