Notes
7. RL = 50 ohm ± 1%; Zline = 50 ohm 6 = Ó.
8. CL includes instrumentation and fixture capacitance within 6 mm of the UT.
9. TPA and B are used for prop delay and rise/fall measurements. TPC is used for VOC measurements only and otherwise connected to VDD – 2.
10. When measuring Tr/Tf, tpd, VOD point TPC is held at VDD – 2.0 V.
11. LVCMOS/LVTTL single-ended input value. Ground either input: when on the B side, non-inversion takes place. If A side is grounded, the signal becomes the
complement of the input on B side. See Function Control of the TTL Input Logic on page 5.

measurement requires equipment with a 3-dB bandwidth of at least 300 MHz.
13. All input pulses are supplied by a frequency generator with the following characteristics: t
R
and t
F
< 1 ns; pulse re-rate = 50 Mpps; pulse width = 10 0.2 ns.

Notes
14. Stresses greater than those listed under absolute maximum ratings may cause permanent damage to the device. This is intended to be a stress rating only and
functional operation of the device at these or any other conditions above those indicated in the operation sections of this specification is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect reliability.
15. Multiple Supplies: The voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
