 These ICs were manufactured in the former German socialist republic 1985, are new and work perfectly named D121D General Description The DM54/74121 is a monostable multivibrator featuring both positive and negative edge triggering with complemen- tary outputs. An internal 2k X timing resistor is provided for design convenience minimizing component count and lay- out problems. This device can be used with a single external capacitor. Inputs (A) are active-low trigger transition inputs and input (B) is an active-high transition Schmitt-trigger in- put that allows jitter-free triggering from inputs with tran- sition rates as slow as 1 volt/second. A high immunity to V CC noise of typically 1.5V is also provided by internal cir- cuitry at the input stage. To obtain optimum and trouble free operation please read operating rules and NSC one-shot application notes careful- ly and observe recommendation Features Y Triggered from active-high transition or active-low tran- sition inputs Y Variable pulse width from 30 ns to 28 seconds Y Jitter free Schmitt-trigger input Y Excellent noise immunity typically 1.2V Y Stable pulse width up to 90% duty cycle Y TTL, DTL compatible Y Compensated for V CC and temperature variations Y Input clamp diodes Y Alternate Military/Aerospace device (54121) is avail- able. Contact a National Semiconductor Sales Office/ Distributor for specifications.
