- Designing With Logic (Rev. C)PDF, 186 Kb, 修订版: C, 档案已发布: Jun 1, 1997
Data sheets which usually give information on device behavior only under recommended operating conditions may only partially answer engineering questions that arise during the development of systems using logic devices. However information is frequently needed regarding the behavior of the device outside the conditions in the data sheet. Such questions might be:?How does a bus driver behave w - Designing with the SN54/74LS123 (Rev. A)PDF, 118 Kb, 修订版: A, 档案已发布: Mar 1, 1997
The Texas Instruments (TI) SN54/74LS123 dual retriggerable monostable multivibrator is a one-shot device capable of verylong output pulses and up to 100% duty cycle. The ?LS123 also features dc triggering from gated low-level active A andhigh-level active B inputs and provides a clear input that terminates the output pulse of any predetermined time independentof timing components R ext and
