74LVT16245 74LVTH16245 Low Voltage 16-Bit Transceiver with 3-STATE Outputs January 1999 Revised November 1999 74LVT16245 74LVTH16245 Low Voltage 16-Bit Transceiver with 3-STATE Outputs General Description The LVT16245 and LVTH16245 contain sixteen non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. Each byte has separate control inputs which can be shorted together for full 16-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 LVTH16245 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 LVT16245 and LVTH16245 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 pullup resistors to hold unused inputs (74LVTH16245), also available without bushold feature (74LVT16245). 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 Functionally compatible with the 74 ser...
