74LVT32245 74LVTH32245 Low Voltage 32-Bit Transceiver with 3-STATE Outputs March 2002 Revised June 2002 74LVT32245 74LVTH32245 Low Voltage 32-Bit Transceiver with 3-STATE Outputs General Description The LVT32245 and LVTH32245 contain thirty-two noninverting bidirectional buffers with 3-STATE outputs and are intended for bus oriented applications. The devices are byte controlled. Each byte has separate control inputs which can be shorted together for full 32-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state. The LVTH32245 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs. These non-inverting transceivers are designed for low voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT32245 and LVTH32245 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation. Features s Input and output interface capability to systems at 5V VCC s Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH32245), also available without bushold feature (74LVT32245). s Live insertion/extraction permitted s Power Up/Down high impedance provides glitch-free bus loading s Outputs source/sink −32 mA/+64 mA s ESD performance: Human-body model > 200...
