    • A photocoupler used for splitting signal light in an optical transmission line at a predetermined ratio. A substrate is provided with a single-layer beam splitter formed by vacuum depositing a film material having a refractive index below a square root of the refractive index of the substrate so that an optical film thickness attains a predetermined value, and means for holding the single-layer beam splitter in the optical transmission line so that the angle of incidence is kept at about 45 . Alternatively, four-, five- or seven-layered thin film is formed by using three kinds of film materials having refractive indices of 1.46 +- 0.10, 1.65 +- 0.10 and 2.30 +- 0.10, respectively, on a substrate having a refractive index of 1.51 +- 0.10 or 3.50 +- 0.20, and the combination of the thin film layers and the optical film thickness of each thin film layer are selected so that dependence of a split ratio on polarized wave becomes small, and a branching film can be formed. The photocoupler further includes this beam splitter and means for holding the beam splitter in the optical transmission line at an angle of about 45 . Furthermore, the photocoupler may comprise a beam splitter formed by forming 4- to 14-layered thin film layer using two kinds of film materials having refractive indices of 1.46 +- 0.10 and 2.30 +- 0.10 on a substrate having a refractive index of 1.51 +- 0.10 to 3.50 +- 0.20 and selecting the combination of the thin film layers and the optical film thickness of each layer so that the dependence of the split ratio on polarized wave becomes small, and means for holding the beam splitter in the optical transmission line at an angle of about 45 .

    • A circuit (300) combines the functions of a logic gate (310, 320) and a latch (330) to lower steady state power dissipation during gate operation. The circuit operates in two modes, a flow-through mode and a latched node. In the flow-through mode, a gate portion (310) which receives one or more digital input signals (X1-XN) implements the complement of a desired Boolean logic function on the input signals and provides an internal signal. The gate portion may have a steady-state power dissipation while providing the internal signal. An inverter (350) in a latch portion (330) of the circuit inverts the internal signal to generate an output signal (Z) which represents the desired logical combination of the input signals. The inverter provides the output signal with a full-range CMOS voltage. In latched mode, the gate portion is disabled to stop the steady-state power dissipation while the latch portion of the circuit preserves the desired output signal.
    • 电路(300)将逻辑门(310,320)和锁存器(330)的功能组合以在门操作期间降低稳态功率耗散。 电路工作在两种模式,即流通模式和锁存节点。 在流通模式中,接收一个或多个数字输入信号(X1-XN)的门部分(310)在输入信号上实现所需的布尔逻辑函数的补码并提供内部信号。 栅极部分可以具有稳态功率耗散,同时提供内部信号。 电路的锁存部分(330)中的反相器(350)使内部信号反相以产生表示输入信号的期望逻辑组合的输出信号(Z)。 逆变器为输出信号提供全范围CMOS电压。 在锁存模式下,禁止门极部分停止稳态功耗,同时电路的锁存部分保留所需的输出信号。
