Low Voltage 16-Bit Transceiver with 3-STATE Outputs and 25 Ohm Series Resistors in A Port Outputs

Key Features

• Input and output interface capability to systems at 5V VCC

• Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH162245), also available without bushold feature (74LVT162245).

• Live insertion/extraction permitted

• Power Up/Down high impedance provides glitch-free bus loading

• A Port outputs include equivalent series resistance of 25ohm making external termination resistors unnecessary and reducing overshoot and undershoot

• A Port outputs source/sink ±12 mA. B Port outputs source/sink -32 mA/+64 mA

• Functionally compatible with the 74 series 162245

• Latch-up performance exceeds 500 mA

• ESD performance:Human-body model > 2000VMachine model > 200VCharged-device model > 1000V

• Also packaged in plastic Fine Pitch Ball Grid Array (FBGA)

Description

The LVT162245 and LVTH162245 contains 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 LVT162245 and LVTH162245 are designed with equivalent 25ohm series resistance in both the HIGH and LOW states on the A Port outputs. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus transceivers/transmitters. The LVTH162245 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) VCCapplications, but with the capability to provide a TTL interface to a 5V environment. The LVT162245 and LVTH162245 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.
