74LVTH162245

Features:

Input and output interface capability to systems at 5V VCC
Bushold data inputs eliminate the need for external pullup 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 25: making external termination resistors unnecessary and reducing overshoot and undershoot
A Port outputs source/sink r12 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 ! 2000V Machine model ! 200V Charged-device model ! 1000V
Also packaged in plastic Fine Pitch Ball Grid Array (FBGA)

Description

The 74LVTH162245 contains sixteen noninverting 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 nputs 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 74LVTH162245 are designed with equivalent 25: 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) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The 74LVTH162245 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.
