CY74FCT16827T中文资料具有 TTL 兼容型 CMOS 输入和三态输出的 20 通道、4.5V 至 5.5V 缓冲器数据手册TI规格书

描述 Description

The CY74FCT16827T 20-bit buffer/line driver and the CY74FCT162827T 20-bit buffer/line driver provide high-performance bus interface buffering for wide data/address paths or buses carrying parity. These parts can be used as a single 20-bit buffer or two 10-bit buffers. Each 10-bit buffer has a pair of NANDed OE\\ for increased flexibility. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The CY74FCT16827T is ideally suited for driving high-capacitance loads and low-impedance backplanes. The CY74FCT162827T has 24-mA balanced output drivers with current-limiting resistors in the outputs. This reduces the need for external terminating resistors and provides for minimal undershoot and reduced ground bounce. The CY74FCT162827T is ideal for driving transmission lines.
