概述

Description

SN74LVT16245BDLR is a 16‑bit bidirectional buffer/driver (bus transceiver) with tri‑state outputs. It links two 16‑bit buses (A and B). A DIR pin selects data flow direction (A→B or B→A); an OE pin enables/disables the outputs. When OE is deasserted, outputs go high-impedance, letting multiple devices share the bus. It belongs to the low‑voltage LVT family, typically operating from about 1.65 V to 3.6 V, with TTL‑compatible inputs and high‑speed, low‑power operation. Suitable for buffering or level shifting between components on different voltage domains, microcontrollers, memory interfaces, or other embedded system interconnects. Features include 16‑bit width, single‑chip transceiver, 3‑state outputs, fast switching, and ESD protection. Package: BDLR indicates a lead‑free, RoHS‑compliant package variant.

Features

Key features of SN74LVT16245BDLR:
- 16-bit bidirectional bus transceiver (two 8-bit ports: A0–A7 and B0–B7)
- DIR input selects data flow direction (A→B or B→A)
- OE input provides 3-state outputs (active-low OE)
- 3-state outputs for bus sharing and tri-stating
- LVT: low-voltage TTL input thresholds; Vcc range 1.65 V to 3.6 V
- CMOS/TTL-compatible I/O levels
- Pb-free (BDLR package) and RoHS compliant
- Suitable for buffering/bus interfacing, memory interfaces, and backplane/app bus buffering
(Note: Always consult the datasheet for exact electrical characteristics and recommended operating conditions.)

Package

20-pin D‑package (SOIC) type.

Pinout

- Pin count: 40 pins (40-pin package).
- Function: 16-bit bidirectional bus transceiver/buffer. It connects two 16-bit data buses (A0–A15 and B0–B15); DIR selects the direction (A↔B), OE enables/disables the outputs, and the outputs are tri‑state when disabled.

Manufacturer

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

Application

- 16-bit bidirectional bus transceiver with 3-state outputs for level shifting between 3.3V and 5V logic
- Interface/buffer between MCUs/FPGAs and memory devices (RAM/ROM/EEPROM) on mixed voltages
- Data/address bus buffering to reduce fan-out and load
- Bidirectional inter-board/backplane or expansion bus interconnects in embedded systems
- General high-speed, low-power data paths for microcontrollers, FPGAs, DSPs in industrial/embedded applications

Equivalent

Equivalent parts are other 16‑bit bidirectional bus transceivers with 3‑state outputs in the same voltage range. Common cross‑references include:
- NXP/Nexperia: 74LVT16245
- Renesas: uPD16245 family
