Visão Geral

Description

74AVC4T245BZX is a 4‑bit bidirectional bus transceiver with dual‑supply level shifting. It provides four data lines that can transfer in either direction between two voltage domains (A side with VCCA and B side with VCCB). Data flow direction is controlled by a DIR input, and the outputs can be tri‑stated with an enable control. This device is used to buffer and translate signals between logic operating at different voltages (for example, a microcontroller at one level and a peripheral at another). It combines high‑speed CMOS performance with low power in a small package. The BZX suffix denotes a specific package/marking variant (RoHS-compliant, lead‑free).

Equivalent

Typical equivalents (same function: 4-bit bidirectional bus transceiver with dual supplies and 3-state outputs) are:
- TI SN74AVC4T245
- Nexperia 74AVC4T245
For exact packaging/temperature variants, use the vendors’ cross-reference tools.

Features

74AVC4T245BZX features (concise):
- 4-bit bidirectional bus transceiver with 3-state outputs (A-side and B-side, 4 lines each)
- DIR input controls data direction (A→B or B→A)
- OE (Output Enable, active low) tri-states both sides when high
- Separate supply rails for each side (VCCA and VCCB), enabling level shifting between voltage domains
- CMOS/TTL-compatible inputs; low power yet high-speed operation
- Suitable for interfacing microcontrollers to memories or peripherals across different voltages
- ESD protection and robust overall device protection; RoHS-compliant packaging (typical 20-pin)
- Fast propagation with low static/dynamic power consumption
Uses: bus isolation, voltage-level translation between buses, and buffering in mixed-voltage systems.

Pinout

- Pin count: 16 pins (SOP/TSSOP style in the BZX package).
- Function: 4-bit, dual-supply bidirectional bus transceiver/level shifter with tri-state outputs. A pins operate on VCCA, B pins on VCCB. DIR selects direction (A→B or B→A); OE enables/disables the outputs. Used to translate between two voltage domains.

Manufacturer

Manufacturer: Nexperia. Nexperia is a global semiconductor company (based in the Netherlands, formerly part of Philips/NXP) that designs and manufactures discrete components and integrated circuits, including logic and analog devices. They supply standard CMOS logic parts like the 74AVC4T245 family for automotive, industrial, and consumer electronics applications.

Application

Application areas of 74AVC4T245BZX:
- Voltage-level translation and buffering between two voltage domains (e.g., 3.3V ↔ 5V, or other domain pairs) with bidirectional data flow.
- 4-bit bidirectional bus transceiver with tri-state outputs for connecting microcontrollers/FPGA to memories, peripherals, or sensors without bus contention.
- Bus isolation/expansion in embedded systems, portable electronics, automotive, and industrial equipment.
- Reconfigurable data paths on backplanes or SoC-to-peripheral interfaces, using DIR and enable control for flexible I/O interfacing.
