Test Specifications
Note: Table 22 through Table 32 and Figure 14 through Figure 23 represent the performance
specifications of the LXT350 and are guaranteed by test except, where noted, by design. The
minimum and maximum values listed in Table 24 through Table 32 are guaranteed over the
recommended operating conditions specified in Table 23.

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 75 Ω load over operating range for T1 operation or 60 Ω load for E1 operation. Includes
power dissipation on device and load. Digital levels are within 10% of the supply rails and digital outputs driving a 50 pF
capacitive load.
