74LVT245B 3.3 V octal transceiver with direction pin (3-state) Rev. 02 8 May 2008 Product data sheet 1. General description The 74LVT245B 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. The device features an output enable (OE) input for easy cascading and a direction (DIR) input for direction control. 2. Features n 3-state buffers n Octal bidirectional bus interface n Input and output interface capability to systems at 5 V supply n TTL input and output switching levels n Output capability: +64 mA/- 32 mA n Latch-up protection exceeds 500 mA per JEDEC Std 17 n ESD protection: u HBM JESD22-A114E exceeds 2000 V u MM JESD22-A115-A exceeds 200 V n Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs n Live insertion/extraction permitted n Power-up 3-state n No bus current loading when output is tied to 5 V bus 3.
