Visão Geral

Description

The SN74AVC32T245ZRLR is TI’s 32‑bit, dual‑supply, noninverting bus transceiver with 3‑state outputs and bidirectional voltage level translation. It provides A[31:0] to B[31:0] data paths that can move in either direction depending on the DIR control, allowing interfaces between two voltage domains (VCCA and VCCB). An output‑enable (OE) tri‑states the bus when deasserted. It’s part of the AV C family and supports fast, low‑power operation with two supply rails in the roughly 1.65–3.6 V range. The ZRLR suffix indicates RoHS‑compliant, lead‑free packaging in a tape‑and‑reel option. Typical uses include level shifting and buffering between microcontrollers, memories, and peripherals across different logic levels.
Note: check the datasheet for exact electrical specs, pinout, and timing details.

Equivalent

Equivalent parts are other vendors’ 32‑bit bidirectional bus transceivers with tri‑state outputs (74AVC/ALVC families). Examples:
- Nexperia: 74AVC32T245
- On Semiconductor: ALVC32T245
Note: verify pinout, Vcc ranges, and timing; use TI cross-reference to ensure true drop-in compatibility for your package (ZRLR) and spec needs.

Features

Here are the key features of SN74AVC32T245ZRLR (concise):
- 32-bit bidirectional bus transceiver with 3-state outputs (four 8-bit banks).
- Dual-supply level shifting: A-side on VCCA and B-side on VCCB for voltage-domain translation.
- Direction control via DIR pin; data flow selectable A-to-B or B-to-A.
- Global output enable via OE for tri-state control of all I/O.
- Ioff support: partial-power-down protection to prevent back-powering when a domain is off.
- ESD protection on all I/O pins; designed for robust, high-speed operation.
- Low-power CMOS technology with fast, dense buffer/translator implementation.
- Package: ZRLR (leadless, compact) suitable for high-density designs.
Note: VCCA/VCCB ranges and exact speed/drive specs are in the TI datasheet; the above captures typical features.

Pinout

- Pin count: 40 pins (40-pin package; RoHS-compliant ZRLR version).
- Function: 32-bit bidirectional bus transceiver with tri‑state outputs. It provides two 16‑bit sides (A and B) that can transfer data in either direction, controlled by a direction input (DIR) and an output‑enable control, suitable for buffering/voltage‑domain translation between two buses.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor design and manufacturing company that produces analog, mixed-signal, and digital ICs, headquartered in Dallas, Texas.

Application

SN74AVC32T245ZRLR is a 32‑bit, dual‑supply, tri‑state bus transceiver with direction control for bidirectional level translation. It translates between different logic-voltage domains (e.g., 2.5/3.3V to 5V). Applications include:
- Interfacing MCUs/SoCs with memories or peripherals at different voltages
- Bridging data/address buses between FPGAs/ASICs/DSPs and memory or I/O devices
- Backplane/inter‑chip communication and I/O expansion
- General high-speed, low-power parallel data paths that require shared, tri‑state buses in consumer, automotive, and industrial equipment

Package

Pb-free, RoHS-compliant 64-pin TQFP (thin quad flat pack) in Tape‑and‑Reel packaging.
