FAIRCHTLD 高速触发器 H11L1SR2M
FAIRCHTLD 高速触发器 H11L1SR2M
简单的是由两个或非门，两个输入端和两个输出端组成的RS触发器。复杂一些的有带时钟段和D(Data)端，在CLK端为高电平时跟随D端状态，而在CLK端变为低电平的瞬间锁存信号的D触发器。更常用的是两个简单D触发器级联而成的在时钟下跳沿所存信号的边缘D触发器，广泛应用于计数器、运算器、存储器等电子部件。

DESCRIPTION
The H11LXM series has a high speed integrated circuit detector optically
coupled to a gallium-arsenide infrared emitting diode. The output incorporates a Schmitt trigger, which provides hysteresis for noise immunity and
pulse shaping. The detector circuit is optimized for simplicity of operation
and utilizes an open collector output for maximum application flflexibility.
FEATURES
• High data rate, 1 MHz typical (NRZ)
• Free from latch up and oscilliation throughout voltage and temperature
ranges.
• Microprocessor compatible drive
• Logic compatible output sinks 16 mA at 0.4 V maximum
• Guaranteed on/off threshold hysteresis
• Wide supply voltage capability, compatible with all popular logic systems
• Underwriters Laboratory (UL) recognized—fifile #E90700, Volume 2
• VDE recognized – File#102497 – Add option V (e.g., H11LIVM)
APPLICATIONS
• Logic to logic isolator
• Programmable current level sensor
• Line receiver—eliminate noise and transient problems
• A.C. to TTL conversion—square wave shaping
• Digital programming of power supplie
• Interfaces computers with peripherals
