Technical Specifications

The PI74LCX245L operates from a supply voltage range of 2.3V to 3.6V. Its inputs are TTL compatible, which simplifies interfacing with older 5V logic. The operating temperature range is -40°C to +85°C. The direction control (DIR) input determines the direction of data flow through the device. The output enable (OE) input controls the 3-state outputs. When OE is high, the outputs are disabled. The device is available in SOIC (Small Outline Integrated Circuit) package. It adheres to RoHS standards.
