74ALVC162245T集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

General Description

The ALVC162245 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 3-STATE 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 74ALVC162245 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O compatibility up to 3.6V.

The 74ALVC162245 is also designed with 26Ω series resistance in the A Port outputs. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus transceivers/transmitters.

The 74ALVC162245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.
