74LVTH322245
3.3 V 32-bit bus transceiver with 30 termination resistors; 3-state
Rev. 01 -- 24 January 2007 Product data sheet
1. General description
The 74LVTH322245 is a high-performance BiCMOS product designed for VCC operation at 3.3 V. The 74LVTH322245 is designed with 30 series resistance in both the HIGH and LOW states of the output. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus receivers/transmitters. The 74LVTH322245 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.

Stresses beyond those listed may cause permanent damage to the device. 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.

All typical values are at VCC = 3.3 V and Tamb = 25 C unless otherwise specified. Unused pins at VCC or GND. This is the bus-hold overdrive current required to force the input to the opposite logic state. This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 3.3 V 0.3 V a transition time of 100 s is permitted. This parameter is valid for Tamb = 25 C only. ICC is measured with outputs pulled to VCC or GND. This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
