产品信息

The MC74LCX245 is a high performance, non-inverting octal transceiver operating from a 2.0 to 5.5V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A V
specification of 5.5V allows MC74LCX245 inputs to be safely driven from 5V devices. The MC74LCX245 is suitable for memory address driving and all TTL level bus oriented transceiver applications.
Current drive capability is 24mA at both A and B ports. The Transmit/Receive (T/Rbar) input determines the direction of data flow through the bi-directional transceiver. Transmit (active-HIGH) enables data from A ports to B ports; Receive (active-LOW) enables data from B to A ports. The Output Enable input, when HIGH, disables both A and B ports by placing them in a HIGH Z condition.

MC74LCX245MNTWG	ON	MC74LCX245 是一款高性能非反向八路收发器，运行电压为 2.0 V 到 5.5V。高阻抗 TTL 兼容输入显著减少了输入驱动器的电流负载，而 TTL 兼容输出则提高了开关噪音性能。5.5V 的 VI 规格使得 MC74LCX245 输入能够基于 5V 器件进行安全驱动。MC74LCX245 适用于内存地址驱动和所有 TTL 级总线导向收发器应用。电流驱动能力在 A 和 B 端口均为 24mA。发射/接收 (T/Rbar) 输入决定了数据流经双向收发器的方向。发射（有效高电平）让数据能够从 A 端口流向 B 端口；接收（有效低电平）则让数据能够从 B 端口流向 A 端口。输出启用输入如果为高电平则会将 A 端口和 B 端口置于高电平 Z 状态，从而将两者禁用。	立即购买
