Test Specifications
Note:
Table 23 through Table 34 and Figure 12 through Figure 21 represent the performance
specifications of the LXT361 and are guaranteed by test except, where noted, by design. The
minimum and maximum values listed in Table 25 through Table 34 are guaranteed over the
recommended operating conditions specified in Table 24.

Caution: Exceeding these values may cause permanent damage.
Caution: Functional operation under these conditions is not implied.
Caution: Exposure to maximum rating conditions for extended periods may affect device reliability.
1. TVCC and VCC must not differ by more than 0.3 V during operation. TGND and GND must not differ by more than 0.3 V
during operation.
2. Transient currents of up to 100 mA will not cause SCR latch-up. TTIP, TRING, TVCC, and TGND can withstand continuous
currents of up to 100 mA.

1. Typical figures are at 25 °C and are for design aid only; not guaranteed and not subject to production testing.
2. TVCC and VCC must not differ by more than 0.3 V.
3. Power dissipation while driving 100
Ω load coupled through 1:1.15 transformer and 0 Ω resistor on TTIP/TRING. Includes
power dissipation on device and load. Digital levels are within 10% of the supply rails and digital outputs driving a 50 pF
capacity load.
4. Power dissipation while driving 100
Ω load coupled through 1:2 transformer and 9.1 Ω resistor on TTIP/TRING. Includes
power dissipation on device and load. Digital levels are within 10% of the supply rails and digital outputs driving a 50 pF
capacity load. This implementation has better return loss performance and is less sensitive to changes in impedances
variations.
5. Power dissipation while driving 120
Ω load coupled through 1:2 transformer and 9.1 Ω resistor on TTIP/TRING. Includes
power dissipation on device and load. Digital levels are within 10% of the supply rails and digital outputs driving a 50 pF
capacity load.
