19. CHARACTERISTICS AND SPECIFICATIONS
19.1 Absolute Maximum Ratings
CAUTION: Operations at or beyond these limits may result in permanent damage to the device. Normal operation
is not guaranteed at these extremes.
19.2 Recommended Operating Conditions
Notes: 1. Human Body Model
2. Transient current of up to 100 mA will not cause SCR latch-up. Also TTIP, TRING, TV+ and TGND can
withstand a continuous current of 100 mA.
3. Power consumption while driving line load over the full operating temperature and power supply voltage
range. Includes all IC channels and loads. Digital inputs are within 10% of the supply rails and digital
outputs are driving a 50pF capacitive load.
4. Typical consumption corresponds to 50% ones density for E1/T1/J1 modes and medium line length
setting for T1/J1 mode at 3.3Volts.
5. Maximum consumption corresponds to 100% ones density for E1/T1/J1 modes and maximum line
length settings for T1/J1 mode at 3.465Volts.
6. This specification guarantees TTL compatibility (VOH = 2.4 V @ IOUT = -400 μA).
7. Output drivers are TTL compatible.
8. Pulse amplitude measured at the output of the transformer across a 75
Ω load.
9. Pulse amplitude measured at the output of the transformer across a 120
Ω load.
10. Pulse amplitude measured at the output of the transformer across a 100
Ω load for all line length
settings.
