NOTES: (1) Logic high enables output (normal operation). (2) Negative conventional current flows out of the terminals. (3) Constant dc output to PWM (pulse-width

modulated) time. (4) Maximum delay is determined by an external capacitor. Pulling the Delay Adjust pin low corresponds to an infinite (continuous) delay.

(5) Connecting the Delay Adjust pin to +5V reduces delay time to 3

µs. (6) V
