SN74LV4T00PWR

Inverter Gates Overview

The SN74LV4T00PWR is a quadruple 2-input positive-NAND gate with integrated voltage translation, manufactured by Texas Instruments. It operates within a supply voltage range of 1.6 V to 5.5 V and supports standard pinouts in a 14-pin TSSOP package. The device features Schmitt-trigger inputs for noise immunity and balanced CMOS outputs capable of driving up to ±15 mA at 3.3 V or 5.0 V supplies. It facilitates single-supply level translation between various CMOS logic families.

Inverter Gates Feature Summary

• Integrated voltage translation supporting both up-translation from lower voltages and down-translation from higher voltages via enhanced input thresholds.
• Schmitt-trigger inputs provide improved noise filtering and tolerance for slow input transition rates.
• Balanced CMOS three-state outputs ensure symmetric sourcing and sinking capabilities across the operating voltage range.

Inverter Gates Applications

• Translation between communication modules and system controllers
• Enabling or disabling digital signals
• Controlling indicator LEDs

Inverter Gates Procurement Notes

Verify that the ordering suffix 'PWR' corresponds to the TSSOP-14 package configuration required for your PCB layout. Confirm that the specific revision of the datasheet matches the production lot date code. Ensure that input pins are terminated to VCC or GND if unused to prevent floating states and excessive power consumption during operation.

Inverter Gates Selection Notes

Select this component when interfacing logic circuits operating at different voltage levels, such as translating between 1.8 V, 2.5 V, 3.3 V, and 5.0 V domains. It is suitable for applications requiring Schmitt-trigger noise immunity on inputs. Ensure the load capacitance does not exceed 50 pF to maintain specified switching characteristics and signal integrity.

Inverter Gates Part Context

This device belongs to the LVxT family of logic ICs from Texas Instruments, designed specifically for low-voltage applications with integrated level-shifting capabilities. The SN74LV4T00 variant provides four independent NAND gates, distinguishing it from other logic functions like inverters or buffers within the same series.

Inverter Gates Replacement Considerations

Direct replacements include SN74LV4T00BQA (WQFN package) or SN74LV4T00PWREP (Enhanced Product). Verify package dimensions and thermal pad requirements when substituting.

Inverter Gates FAQ

How does the device handle slow input transitions?

The SN74LV4T00 utilizes Schmitt-trigger inputs, which allow it to tolerate slow input transition rates without causing oscillations or excessive power consumption, unlike standard CMOS inputs.

What is the maximum input voltage tolerance?

The input pins are tolerant of signals up to 5.5 V, enabling down-translation from higher voltage logic families even when the device is powered by lower supply voltages.
