SN54LS221J Description

Short technical summary and product information.

The SN54LS221J from Texas Instruments is a dual monostable multivibrator designed for reliable timing applications. This component features two independent multivibrators, each with a negative-transition-triggered input and a positive-transition-triggered input that can also function as an inhibit input. The Schmitt-trigger circuitry on the B input provides excellent noise immunity, allowing for jitter-free triggering even with slow input transition rates.

 

Key electrical characteristics include a supply current of 27000µA, a maximum IOL of 4mA, and a maximum IOH of -0.4mA. The device operates within a temperature range of -55°C to 125°C, making it suitable for military applications. The output pulse length can be adjusted by external components, offering flexibility in design.

 

Available in CFP, CDIP, and LCCC packages, the SN54LS221J is designed for through-hole mounting. Its robust design and stable performance make it a suitable choice for various timing and pulse generation circuits where high reliability is required.
