Adjustable Delay (CDELAY)
When VIN rises above VTH with ENABLE high (ENABLE
low), the internal 250nA current source begins charging
an external capacitor connected from CDELAY to GND.
When the voltage at CDELAY reaches 1V, the output
asserts (OUT goes high or OUT goes low). When the
output asserts, CCDELAY is immediately discharged.
Adjust the delay (tDELAY) from when VIN rises above
VTH (with ENABLE high or ENABLE low) to OUT going
high (OUT going low) according to the equation:
tDELAY = CCDELAY x 4.0 x 10-6 + 40s
where CCDELAY is the external capacitor from CDELAY
to GND.
For adjustable delay devices (A version), when VIN >
0.5V and ENABLE goes from low to high (ENABLE
goes from high to low) the output asserts after a tDELAY
period. For nonadjustable delay devices (P version)
there is a 1s propagation delay from when the enable
input is asserted to when the output asserts. Figures 2
through 5 show the timing diagrams for the adjustable
and fixed delay versions, respectively.
