These devices are precision timing circuits capable of producing accurate time delays or oscillation.In the time-delay or monostable mode of operation,the timed interval is controlled by a single external resistor and capacitor network.In the astable mode of operation,the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor.The threshold and trigger levels normally are two-thirds and one-third,respectively,of VCC.These levels can be altered by use of the control-voltage terminal.When the trigger input falls below the trigger level,the flip-flop is set and the output goes high.If the trigger input is above the trigger level and the threshold input is above the threshold level,the flip-flop is reset and the output is low.The reset (RESET) input can override all other inputs and can be used to initiate a new timing cycle.When RESET goes low,the flip-flop is reset and the output goes low.When the output is low,a low-impedance path is provided between discharge (DISCH) and ground.The output circuit is capable of sinking or sourcing current up to 200 mA.Operation is specified for supplies of 5 V to 15 V.With a 5-V supply,output levels are compatible with TTL inputs.

Answer 1

这些器件是能够产生精确时延或振荡的精确计时电路.在时延或单稳态操作模式下,计时间隔由一个单独的外部电阻电容网络控制.在不稳态操作模式下,频率和占空因数可以由两个外部电阻和一个外部电容分别控制.阈值和触发电平一般分别是VCC的1/3和2/3.这些电平值可以用控制电压终端改变.当触发输入低于触发电平时,触发器被触发,输出高电平.如果触发输入高于触发电平并且阈值输入在阈值电平之上,触发器被重置,输出低电平.“复位”（RESET）输入端可以重载所有其他的输入并可以被用于初始化一个新的计时周期.当RESET信号变低时,触发器复位,输出低电平.当输出端为低电平时,在放电端（DISCH）和地之间出现一个低阻抗通路.输出电路有能力接收或发出高至200mA的电流.操作要在5V至15V的电压下进行.用5V的电源,输出电平与TTL输入兼容.
