Characteristic Performance requirement Reference information
Ground Closure Input
signaling
TTL thresholds, 5 V max
input, –0.5 V min input. P ull
low to assert.
Has internal 10 kΩ pull-up to 5 V on each input. D irect or
encoded inputs m ust be asserted and stable for at least 150 ms
to be recognized reliably. Inputs that are stable for 75 ms or less
will never be recognized.
