74ALVT162827DL数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

20-bit buffer/line driver, non-inverting,with 30Ohm termination resistors (3-State) - The 74ALVT162827 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. It is designed for VCC operation at 2.5 V or 3.3 V with I/O compatibility to 5 V. The 74ALVT162827 20-bit buffers provide high performance bus interface buffering for wide data/address paths or buses carrying parity. They have NOR Output Enables (nOE1, nOE2) for maximum control flexibility. The 74ALVT162827 is designed with 30 Ω series resistance in both the pull-up and pull-down output structures. This design reduces line noise in applications such as memory address drivers, clock drivers and bus receivers/transmitters.
