74LVT245 3.3 V octal transceiver with direction pin (3-state) Rev. 4 24 December 2013 Product data sheet 1. General description The 74LVT245 is a high-performance BiCMOS product designed for V operation at CC 3.3 V. This device is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. It features an output enable (OE) input for easy cascading and a direction (DIR) input for direction control. 2. Features and benefits 3-state buffers Octal bidirectional bus interface Input and output interface capability to systems at 5 V supply TTL input and output switching levels Output capability: +64 mA/ 32 mA Latch-up protection exceeds 500 mA per JESD78 class II level A ESD protection: HBM JESD22-A114E exceeds 2000 V MM JESD22-A115-A exceeds 200 V Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs Live insertion/extraction permitted Power-up 3-state No bus current loading when output is tied to 5 V bus 3.
