Description

SN74LVT245BDBR is an 8‑bit bidirectional bus transceiver from TI’s SN74LVT family with 3‑state outputs. It provides two 8‑bit buses (A1–A8 and B1–B8) and data can move in either direction under a DIR control. An OE input tri‑states the outputs when deasserted, allowing multiple devices to share a bus. It operates from a single low‑voltage supply (Vcc typically 1.65–3.6 V) with CMOS/TTL‑compatible inputs. The device is ideal for buffering/bridging between buses or domains (microcontrollers, memories, peripherals) and for sharing data paths in system buses. The suffix DBR indicates the D package (RoHS) in tape‑and‑reel format. Pin examples: A1–A8, B1–B8, DIR, OE, Vcc, GND. For exact electrical specs (timing, drive, leakage, temperature range), refer to the SN74LVT245B datasheet.

Features

Here are the key features of SN74LVT245BDBR:
- Octal, bidirectional bus transceiver with 3-state outputs (A0–A7 and B0–B7)
- DIR input determines direction: AB or BA data flow
- OE (active-low) input to enable/disable the outputs (high-impedance when disabled)
- Supports bus sharing on common data lines
- Wide single-supply operation with low-voltage CMOS/TTL-compatible inputs
- Designed for low power in portable/battery-powered applications
- Part of the LVT family, offering low-voltage operation and compatible interfacing
Typical use: buffering or interfacing between different logic levels or bus architectures in microcontrollers, processors, and peripheral devices.

Package

20-pin Small Outline Integrated Circuit (SOIC) package; BR indicates the Tape‑and‑Reel variant of the standard SOIC (0.300" body width).

Pinout

- Pin count: 20 pins (20-pin package, e.g., SOIC/TSSOP variants).
- Function: Octal bidirectional bus transceiver with 3-state outputs. It provides eight data lines on each side (A1–A8 and B1–B8); a DIR input selects the data flow direction (A→B or B→A), and an OE input tri-states the outputs. Used to connect or isolate two buses and level-shift between them.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: an American multinational semiconductor company that designs and manufactures analog and digital integrated circuits and other electronic components.

Application

SN74LVT245BDBR is an octal bus transceiver with 3-state outputs. Main applications: bidirectional data buffering and level shifting between voltage domains (3.3V/5V); microprocessor/memory bus interfacing and address/data line buffering; interface between ASIC/FPGA and microcontrollers; backplane/inter-board bus drivers; and I/O expansion in consumer electronics, automotive and industrial equipment.

Equivalent

Equivalents to SN74LVT245BDBR (octal bidirectional transceiver with 3-state outputs) include:
- 74LVC245 (NXP/Onsemi/Renesas)
- 74HC245 (NXP/TI)
- 74VHC245 (NXP)
These perform the same function in different voltage families. Check supply ranges and OE/D pin compatibility, as exact electrical specs differ.
