74HC(T)4538: 双可再触发精密单稳态多谐振荡器
74HC4538；74HCT4538是高速硅栅CMOS器件，与低功耗肖特基TTL (LSTTL)针脚兼容。其规格符合JEDEC标准no. 7A。
74HC4538；74HCT4538是双可再触发可复位单稳态多谐振荡器。每个多谐振荡器都具有一个低电平有效触发/再触发输入(nA)、一个高电平有效触发/再触发输入(nB)、一个覆盖低电平有效直接复位输入(nCD)、一个输出(nQ)及其补充输出(nQ)和两个连接外部定时元件CEXT和REXT的针脚（nREXT/CEXT和nCEXT）。额定温度范围内的典型脉冲宽度变化为±0.2 %。
多谐振荡器可通过输入脉冲的正沿或负沿触发。输出脉冲的持续时间和精度由外部定时元件CEXT和REXT确定。输出脉冲宽度(tW)等于0.7 × REXT × CEXT。线性设计技术可保证输出脉冲宽度的精确控制。nCD处的低电平可立即终止输出脉冲。针脚nA和nB上的施密特触发器动作使电路高度容许较慢的上升和下降时间。
