74LVT162245 • 74LVTH162245 Low Voltage 16-Bit Transceiver with 3-STATE Outputs and 25Ω Series Resistors in A Port Outputs January 1999 Revised June 2002 74LVT162245 74LVTH162245 Low Voltage 16-Bit Transceiver with 3-STATE Outputs and 25Ω Series Resistors in A Port Outputs General Description Features The LVT162245 and LVTH162245 contains sixteen non-Input and output interface capability to systems at inverting bidirectional buffers with 3-STATE outputs and is 5V V CC intended for bus oriented applications. The device is byte Bushold data inputs eliminate the need for external pull- controlled. Each byte has separate control inputs which up resistors to hold unused inputs (74LVTH162245), can be shorted together for full 16-bit operation. The T/R also available without bushold feature (74LVT162245). inputs determine the direction of data flow through the Live insertion/extraction permitted device. The OE inputs disable both the A and B ports by Power Up/Down high impedance provides glitch-free placing them in a high impedance state. bus loading The LVT162245 and LVTH162245 are designed with A Port outputs include equivalent series resistance of equivalent 25Ω series resistance in both the HIGH and 25Ω making external termination resistors unnecessary LOW states on the A Port outputs. This design reduces line and reducing overshoot and undershoot noise in applications such as memory address drivers, clock drivers, and bus transceivers/transmitters.A Port outputs source/sink ±12 mA. B Port outputs source/sink −32 mA/+64 mA The LVTH162245 data inputs include bushold, eliminating the need for external pull-up resistors to hold unusedFunctionally compatible with the 74 series 162245 inputs.
