All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50 Ω, tt < 6 ns. For clock inputs, fmax is measured when the input duty cycle is 50%. The outputs are measured one at a time with one input transition per measurement. Test Point From Output Under Test CL(1) (1) CL includes probe and test-fixture capacitance. Figure 6-1.

Each VCC terminal should have a good bypass capacitor to prevent power disturbance. A 0.1-μF capacitor is recommended for this device. It is acceptable to parallel multiple bypass caps to reject different frequencies of noise. The 0.1-μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor should be installed as close to the power terminal as possible for best results. 9 Layout 9.1 Layout Guidelines When using multiple-input and multiple-channel logic devices inputs must not ever be left floating. In many cases, functions or parts of functions of digital logic devices are unused; for example, when only two inputs of a triple-input AND gate are used or only 3 of the 4 buffer gates are used. Such unused input pins must not be left unconnected because the undefined voltages at the outside connections result in undefined operational states. All unused inputs of digital logic devices must be connected to a logic high or logic low voltage, as defined by the input voltage specifications, to prevent them from floating. The logic level that must be applied to any particular unused input depends on the function of the device. Generally, the inputs are tied to GND or VCC, whichever makes more sense for the logic function or is more convenient. 8 Submit Document Feedback Copyright © 2022 Texas Instruments Incorporated Product Folder Links: SN54HCT02 SN74HCT02 SN54HCT02, SN74HCT02 www.ti.com SCLS065G – NOVEMBER 1988 – REVISED OCTOBER 2022 10 Device and Documentation Support TI offers an extensive line of development tools.

For change details, review the revision history included in any revised document. 10.3 Support Resources TI E2E™ support forums are an engineer's go-to source for fast, verified answers and design help — straight from the experts. Search existing answers or ask your own question to get the quick design help you need. Linked content is provided "AS IS" by the respective contributors. They do not constitute TI specifications and do not necessarily reflect TI's views; see TI's Terms of Use. 10.4 Trademarks TI E2E™ is a trademark of Texas Instruments. All trademarks are the property of their respective owners. 10.5 Electrostatic Discharge Caution This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 10.6 Glossary TI Glossary This glossary lists and explains terms, acronyms, and definitions. 11 Mechanical, Packaging, and Orderable Information The following pages include mechanical, packaging, and orderable information.
