CD74HCT221M96规格书详情

CD74HCT221M96属于集成电路(IC)的多谐振荡器。由美国德州仪器公司制造生产的CD74HCT221M96多谐振荡器多谐振荡器是简单的双态器件,尽管它们的典型使用方式在很大程度上具有模拟特性,但通常被认为是数字逻辑元器件。单稳型也称为“单发”,具有一种稳定状态;但施加触发信号可使它们离开此状态一段时间,该时间通常由所连接电容器的值来确定。这些器件对于去弹跳开关触头等应用非常有用。非稳型没有稳定状态,在两个状态之间按一定频率持续转换,该频率通常也是由所连接电容器的值来确定。

描述 Description

The ’HC221 and CD74HCT221 are dual monostable

multivibrators with reset. An external resistor (RX) and an

external capacitor (CX) control the timing and the accuracy

for the circuit. Adjustment of RX and CX provides a wide

range of output pulse widths from the Q and Q terminals.

Pulse triggering on the B input occurs at a particular voltage

level and is not related to the rise and fall time of the trigger

pulse.

Once triggered, the outputs are independent of further trigger

inputs on A and B. The output pulse can be terminated by a

LOW level on the Reset (R) pin. Trailing Edge triggering (A)

and leading-edge-triggering (B) inputs are provided for

triggering from either edge of the input pulse. On power up,

the IC is reset. If either Mono is not used each input (on the

unused device) must be terminated either high or low.

The minimum value of external resistance, RX, is typically 500Ω.

The minimum value of external capacitance, CX, is 0pF. The

calculation for the pulse width is tW = 0.7 RXCX at VCC = 4.5V.
