1. General description
The 74LV123 is a dual retriggerable monostable multivibrator with reset. The basic output pulse
width is programmed by selection of external components (REXT and CEXT). Once triggered this
basic pulse width may be extended by retriggering either of the edge triggered inputs (nA or (nB).
By repeating this process, the output pulse period (nQ = HIGH, nQ = LOW) can be made as long
as desired. Alternatively, an output delay can be terminated at any time by a LOW-going edge on
input nRD. Control inputs include clamp diodes. This enables the use of current limiting resistors
to interface inputs to voltages in excess VCC. Schmitt-trigger action at nA and nB inputs makes the
circuit tolerant of slower input rise and fall times.
2. Features and benefits
? Wide supply voltage range from 1.0 V to 5.5 V
? CMOS low power dissipation
? Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
? Optimized for low-voltage applications: 1.0 V to 3.6 V
? Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V
? Typical output ground bounce: < 0.8 V at VCC = 3.3 V and Tamb = 25 °C
? Typical HIGH-level output voltage (VOH) undershoot: > 2 V at VCC = 3.3 V and Tamb = 25 °C
? DC triggered from active HIGH or active LOW inputs
? Retriggerable for very long pulses up to 100 duty factor
? Direct reset terminates output pulses
? Schmitt-trigger action on all inputs except for the reset input
? Complies with JEDEC standards:
? JESD8-7 (1.65 V to 1.95 V)
? JESD8-5 (2.3 V to 2.7 V)
? JESD8C (2.7 V to 3.6 V)
? JESD36 (4.5 V to 5.5 V)

? MM JESD22-A115-A exceeds 200 V
? Multiple package options
? Specified from -40 °C to +85 °C and from -40 °C to +125 °C
74LV123BQ屬于集成電路(IC) > 多諧振蕩器。安世半導(dǎo)體(中國)有限公司制造生產(chǎn)的74LV123BQ多諧振蕩器多諧振蕩器是簡單的雙態(tài)器件,盡管它們的典型使用方式在很大程度上具有模擬特性,但通常被認(rèn)為是數(shù)字邏輯元器件。單穩(wěn)型也稱為“單發(fā)”,具有一種穩(wěn)定狀態(tài);但施加觸發(fā)信號可使它們離開此狀態(tài)一段時間,該時間通常由所連接電容器的值來確定。這些器件對于去彈跳開關(guān)觸頭等應(yīng)用非常有用。非穩(wěn)型沒有穩(wěn)定狀態(tài),在兩個狀態(tài)之間按一定頻率持續(xù)轉(zhuǎn)換,該頻率通常也是由所連接電容器的值來確定。
