概要
Description
SN74LVT16245BDLR is a 16‑bit, bidirectional bus transceiver with 3‑state outputs. It provides two 16‑bit data ports (A0–A15 and B0–B15) and uses a DIR control to determine the data flow direction (A→B or B→A). An output‑enable (OE) input tri-states the entire 16‑bit bus, allowing multiple devices to share the same bus without contention. The device belongs to the LVT (low‑voltage TTL) family, typically operating from Vcc = 1.65–3.6 V with CMOS/TTL‑compatible inputs and fast switching suitable for high‑speed data transfer. It’s ideal for interfacing two buses with different voltage levels, level shifting, or bus isolation between devices such as MCUs, FPGAs, DSPs, and memories. Packaging code BDLR denotes TI’s small‑outline package variant. In short: a high‑speed, 16‑bit, bidirectional buffer with controllable direction and tri‑state outputs for flexible bus interfacing.

Features
Here are the key features of SN74LVT16245BDLR:
- 16-bit bidirectional bus transceiver with DIR and OE control
- A and B data ports: A0–A15 and B0–B15 (two 8/16-bit sides)
- Direction control: data can flow A→B or B→A depending on DIR
- Output enable (OE) provides true 3-state outputs (high impedance when disabled)
- Partial-power-down support (Ioff) for safe operation when power is removed
- Low-voltage operation: Vcc = 1.65 V to 3.6 V
- TTL/CMOS-compatible input thresholds
- ESD protection on inputs/outputs
- Packaging: BDLR (RoHS-compliant) small-outline package
Note: This device is designed for bus interfacing between two systems and allows flexible, high-speed data transfer with shared buses.

Pinout
- Pin count: 40 pins (DSO/TSSOP-40 style package, BDLR variant).
- Function: 16-bit bidirectional bus transceiver with a single DIR control and an active-low OE (output enable). Data can transfer between the A0–A15 and B0–B15 buses in either direction depending on DIR, and the outputs go high-impedance when OE is deasserted.
