This is partly true because the Schmitt trigger prevents oscillation which can draw a lot of current; however, you will see higher ICC current due to the amount of time the input is not at the rail. This is Delta ICC. Delta ICC is where the inputs are not at the rails and upper or lower drive transistors are partially on. Figure 6-1 shows ICC across the input voltage sweep. Figure 6-1.

These devices perform the Boolean function Y = A. Each circuit functions as an independent inverter, but because of the Schmitt action, the inverters have different input threshold levels for positive-going (VT+) and for negative-going (VT−) signals. 8.2 Functional Block Diagram A Y 8.3 Feature Description • • Inputs are TTL-Voltage compatible Inputs accept very slow or noisy inputs 8.4 Device Functional Modes Table 8-1.

TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality. 9.1 Application Information Schmitt triggers should be used anytime you need to translate a sign wave into a square wave, or used where a slow or noisy input needs to be sped up or cleaned up as in the switch de-bouncer circuit. 9.2 Typical Application 5V 10 kΩ 1/6 W SN74AHCT14 10 nf Circuit Symbol for a Schmitt Trigger Figure 9-1. Switch De-Bouncer Using Schmitt Trigger Inverter 9.2.1 Design Requirements This device uses CMOS technology and has balanced output drive. Care should be taken to avoid bus contention because it can drive currents that would exceed maximum limits. The high drive will also create fast edges into light loads; therefore, routing and load conditions should be considered to prevent ringing. 9.2.2 Detailed Design Procedure 1. Recommended input conditions: • Specified High and low levels: See (VIH and VIL) in the Recommended Operating Conditions table. • Inputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid VCC 2. Recommended output conditions: • Load currents should not exceed 25 mA per output and 50 mA total for the part • Outputs should not be pulled above VCC 10 Submit Document Feedback Copyright © 2022 Texas Instruments Incorporated Product Folder Links: SN54AHCT14 SN74AHCT14 SN54AHCT14, SN74AHCT14 www.ti.com SCLS246R – OCTOBER 1995 – REVISED SEPTEMBER 2022 9.2.3 Application Curves Figure 9-2. Typical Application Curves 10 Power Supply Recommendations The power supply can be any voltage between the MIN and MAX supply voltage rating located in the Recommended Operating Conditions table. Each VCC pin should have a good bypass capacitor to prevent power disturbance. For devices with a single supply, 0.1 μf is recommended. If there are multiple VCC pins, 0.01 μf or 0.022 μf is recommended for each power pin. It is acceptable to parallel multiple bypass caps to reject different frequencies of noise. A 0.1 μf and 1 μf are commonly used in parallel. The bypass capacitor should be installed as close to the power pin as possible for best results.

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 input pins should not be left unconnected because the undefined voltages at the outside connections result in undefined operational states. Figure 11-1 shows the rules that must be observed under all circumstances. All unused inputs of digital logic devices must be connected to a high or low bias to prevent them from floating. The logic level that should be applied to any particular unused input depends on the function of the device. Generally they will be tied to GND or VCC; whichever makes more sense or is more convenient. It is generally acceptable to float outputs unless the part is a transceiver. If the transceiver has an output enable pin, it will disable the outputs section of the part when asserted. This will not disable the input section of the IO’s so they cannot float when disabled. 11.2 Layout Example Vcc Unused Input Input Output Unused Input Output Input Figure 11-1.

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. 12.6 Glossary TI Glossary This glossary lists and explains terms, acronyms, and definitions. 13 Mechanical, Packaging, and Orderable Information The following pages include mechanical, packaging, and orderable information.
