MC10H123中文资料Triple 4-3-3-Input Bus Driver数据手册ONSEMI规格书

描述 Description

The MC10H123 is a triple 4-3-3-Input Bus Driver. The MC10H123 consists of three NOR gates designed for bus driving applications on card or between cards. Output low logic levels are specified with VOL = -2.1 Vdc so that the bus may be terminated to -2.0 Vdc. The gate output, when low, appears as a high impedance to the bus, because the output emitter-followers of the MC10H123 are \"turned-off.\" This eliminates discontinuities in the characteristic impedance of the bus. The VOH level is specified when driving a 25-ohm load terminated to -2.0 Vdc, the equivalent of a 50-ohm bus terminated at both ends. Although 25 ohms is the lowest characteristic impedance that can be driven by the MC10H123, higher impedance values may be used with this part. A typical 50-ohm bus is shown in Figure 1.

简介

MC10H123属于集成电路（IC）的门反相器。由制造生产的MC10H123门和反相器逻辑栅极和逆变器系列中的产品对单个逻辑信号执行基本逻辑运算（例如 AND、NOT、OR 等）。与触发器不同，它们不能够存储信息，不会对提供给其输入的信号立即做出响应。虽然早就被集成电路实施形式所取代，以用于实现复杂功能，但分立栅极仍可在仅需要非常简单逻辑功能的情况下使用。
