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 VCC operation at 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 I I I I I I I I I I 32-bit bidirectional bus interface 3-state buffers Output capability: +64 mA and −32 mA TTL input and output switching levels Input and output interface capability to systems at 5 V supply Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs Live insertion and extraction permitted Power-up 3-state No bus current loading when output is tied to 5 V bus Latch-up protection: N JESD78 Class II level A exceeds 500 mA I ESD protection: N HBM JESD22-A114E exceeds 2000 V N MM JESD22-A115-A exceeds 200 V 3.

These are stress ratings only and functional operation of the device at these or any other conditions beyond indicated under Section 8 “Recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed. [2] [3] 74LVTH32245_1 © NXP B.V. 2008. All rights reserved.
