74LVTH32245 3.3 V 32-bit bus transceiver; 3-state Rev. 01 23 January 2008 Product data sheet 1. General description The 74LVTH32245 is a high-performance BiCMOS product designed for V operation at CC 3.3 V. The 74LVTH32245 is a 32-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The device features four output enable (nOE) inputs for easy cascading and four send/receive (nDIR) inputs for direction control. Pin nOE controls the outputs so that the buses are effectively isolated. Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs. 2. Features n 32-bit bidirectional bus interface n 3-state buffers n Output capability: +64 mA and - 32 mA n TTL input and output switching levels n Input and output interface capability to systems at 5 V supply n Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs n Live insertion and extraction permitted n Power-up 3-state n No bus current loading when output is tied to 5 V bus n Latch-up protection: u JESD78 Class II level A exceeds 500 mA n ESD protection: u HBM JESD22-A114E exceeds 2000 V u MM JESD22-A115-A exceeds 200 V 3.
