Overview

Description

SN74CBT3384ADBQR is a TI 8-bit bidirectional bus transceiver (two 4‑bit buffers) with 3‑state outputs. It lets you move data between two buses or voltage domains using a single direction input (DIR) and an output enable (OE). When OE is active, data can transfer from A to B or B to A depending on DIR; when OE is inactive, the outputs go high impedance.
Key points:
- Two 4-bit channels with bidirectional data flow
- Common DIR control and OE for tri-stating outputs
- Supports operation between different voltage domains (A side vs. B side)
- Fast CMOS, suitable for buffering and level shifting in mixed‑voltage systems
- Useful for microcontroller–peripheral interfaces, memory interconnects, and bus isolation
Packaging: ADBQR indicates RoHS-compliant, tape-and-reel packaging in a specific TI package.
For exact pinout, VCCA/VCCB ranges, timing, and electrical specs, check the TI datasheet: SN74CBT3384A/ADBQR.

Package

QR suffix indicates a RoHS-compliant small-outline package. For SN74CBT3384ADBQR, the package is a 20‑pin TSSOP (small‑outline) package.

Pinout

Pin count: 20 pins.
Function: 4-bit bidirectional bus transceiver (buffer/driver) with direction control and tri‑state (3-state) outputs for level-shifting/transferring four data lines between two sides.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational technology company that designs and manufactures semiconductors and integrated circuits (analog, mixed-signal, and digital processing).

Application

SN74CBT3384ADBQR is a 4-bit bidirectional bus transceiver with voltage translation. Applications:
- Level shifting between two logic domains (e.g., 3.3 V and 5 V)
- Bidirectional data transfer between MCU/FPGA and peripherals on a shared bus
- Buffering/isolating data buses in backplanes, motherboards, or system-on-module designs
- I/O expansion in embedded systems with mixed-supply interfaces
- Interfacing memory or display drivers with different supply voltages
