Preliminary Information
AC Electrical Characteristics
Characteristics
* Typical figure are at 25
°
C with nominal
+
5V supplies and are for design aid only.
AC Electrical Characteristics are over recommended operating conditions unless otherwise stated.
Both of the 2-4 Wire circuits are tested. TX, RX and Junctor actually refer to TX1, RX1 and JUN1; and TX2, RX2 and JUN2.
All of the above test conditions use 754
connected between Junctor and AGND, unless otherwise stated.
All the above test conditions use 200Hz to 3400Hz unless otherwise stated.
Notes:
x
RX is connected to AGND, see Figure 3.
y
See Figure 5.
z
See Figure 4.
