The detector has optical receiver
input stage with built-in Schmitt
trigger to provide logic compatible
waveforms, eliminating the need
for additional waveshaping. The
hysteresis provides differential
mode noise immunity and mini-
mizes the potential for output
signal chatter.
The electrical and switching
characteristics of the HCPL-2400
and HCPL-2430 are guaranteed
over the temperature range of
0°C to 70°C.
These optocouplers are
compatible with TTL, STTL,
LSTTL, and HCMOS logic
families. When Schottky type TTL
devices (STTL) are used, a data
rate performance of 20 MBd over
temperature is guaranteed when
using the application circuit of
Figure 13. Typical data rates are
40 MBd.
