Checking for live stock

The Texas Instruments SN74LVT245BPW is a low‑voltage, octal bus transceiver engineered for seamless data transmission between asynchronous buses. Ideal for professional and industrial applications, its 3.3 V ABT architecture supports a TTL interface to 5 V systems, making it a versatile choice for mixed‑signal environments. Sophisticated Ioff and power-up 3-state design prevents bus contention and backflow during power cycling, safeguarding system integrity in industrial and mission-critical deployments.

Product Key Specifications

  • Material / Package: 20‑pin TSSOP‑20 surface‑mount package (6.5 × 4.4 × 1.15 mm).
  • Supply Voltage: 2.7 – 3.6 V (nominal 3.3 V operation).
  • Channels / Ports: 8‑bit non‑inverting transceiver (bus A ↔ B, controlled via DIR & OE).
  • Output Current: Low‑level: 64 mA; High‑level: –32 mA.
  • Propagation Delay: 2.3 ns typical at 3.3 V, 50 pF load.
  • Temperature Rating: –40 °C to +85 °C operating range.

Unparalleled Benefits to Users
