74LVC2245APW,118 is a 8-bit bidirectional bus transceiver designed for 3.3V logic systems

The 74LVC2245APW,118 is a high-performance, 8-bit bidirectional bus transceiver designed for 3.3V logic systems. Part of the LVC (Low Voltage CMOS) family, it features low power consumption, high speed, and compatibility with both 3.3V and 5V input signals (5V-tolerant inputs). This device enables bidirectional data transfer between two independent bus systems with direction control and output enable functions.

• 8-bit bidirectional data transceiver for parallel data transfer between Bus A (A0-A7) and Bus B (B0-B7)
• Direction control (DIR pin) determines data flow direction (A→B when HIGH, B→A when LOW)
• Output enable (OE pin) activates/deactivates output buffers (LOW=enabled, HIGH=high-impedance state)
• 5V-tolerant inputs for compatibility with 5V logic systems
• Low power consumption (typical ICC < 1 µA at idle)
• High speed operation (typical propagation delay tPD < 5 ns at VCC = 3.3V)

Provides cost-effective level shifting between 3.3V and 5V bus systems, such as connecting 3.3V microcontrollers to 5V peripherals.

Enables data exchange between microcontrollers and external devices (RAM, EEPROM, I/O expanders) or between ADCs and DSPs.

Prevents bus conflicts in multi-master systems and facilitates backplane communication in modular systems.

Ideal for battery-powered devices including medical equipment, wireless sensors, and mobile accessories.

The "PW" suffix indicates a TSSOP-20 (Thin Shrink Small Outline Package) with 20 pins. This compact package (approximately 6.4mm * 3.9mm) is ideal for space-constrained PCB designs.
