SNx4LV221A Dual Monostable Multivibrators with Schmitt-trigger Inputs
1 Features
- 2V to 5.5V VCC operation
- Max tpd of 11ns at 5V
- Support mixed-mode voltage operation on all ports Schmitt-trigger circuitry on A , B, and CLR inputs for slow input transition rates
- Overriding clear terminates output pulse
- Glitch-free power-up reset on outputs
- Ioff supports partial-power-down mode operation
- Latch-up performance exceeds 100mA per JESD 78, class II
2 Description
The ’LV221A devices are dual multivibrators designed for 2V to 5.5V VCC operation. Each multivibrator has a negative-transition-triggered (A) input and a positive-transition-triggered (B) input, either of which can be used as an inhibit input.
