The 74LS221 is a 16-pin dual monostable multivibrator integrated circuit (IC) manufactured by Texas Instruments. It is part of the 74LSxx series of low-power Schottky TTL (LSTTL) logic ICs.Description:The 74LS221 is a dual monostable multivibrator designed to produce accurate and highly stable one-shot pulses with a wide range of trigger and reset inputs. It features two independent, internally-triggered, monostable multivibrators with complementary outputs, each capable of producing a single output pulse of adjustable width when triggered by either a positive or negative edge of the input signal. The output pulse width is adjustable over a wide range, from a few nanoseconds to several hundred microseconds.Features: Wide range of trigger and reset inputs Adjustable output pulse width Complementary outputs Low power consumption Low propagation delay Low noiseApplications: Timing and pulse generation Pulse width modulation Pulse position modulation Frequency division Clock and data recovery Sequential logic circuits Pulse shaping Waveform generation(For reference only)
