74ALVCH162244DL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

2.5 V / 3.3 V 16-bit buffer/line driver (3-state) - The 74ALVCH162244 is a high-performancelow-powerlow-voltageSi-gate CMOS devicesuperior to most advanced CMOS compatible TTL families. The 74ALVCH162244 is a 16-bit non-inverting buffer/line driver with 3-State outputs. The device can be used as four 4-bit bufferstwo 8-bit buffers or one 16-bit buffer. The 3-State outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high impedance OFF-state. The 74ALVCH162244 is designed with 30 Ω series resistors in both HIGH and LOW output states. The 74ALVCH162244 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors.
