SNJ54L123J TI Logic IC | Dual Retriggerable Monostable Multivibrator | 4.5V-5.5V, -55°C to +125°C

Product Overview

The SNJ54L123J is a dual retriggerable monostable multivibrator from Texas Instruments, designed for high-reliability military and aerospace applications. Each multivibrator features an active-low trigger (A) and an active-high trigger (B) input, along with a clear (CLR) input for resetting the output pulse. The device provides output pulse width control via external resistors and capacitors, making it ideal for precision timing applications. Housed in a ceramic DIP package, the SNJ54L123J operates over the full military temperature range of -55°C to +125°C and is compliant with MIL-STD-883 standards.
