MC74VHC14DTG

Inverter Gates Overview

The MC74VHC14DTG is a hex Schmitt inverter fabricated with silicon gate CMOS technology. It operates within a supply voltage range of 2.0 V to 5.5 V and supports an operating temperature from -55°C to +125°C. The device features balanced propagation delays with a typical tPD of 5.5 ns at VCC = 5.0 V. It provides high noise immunity with hysteresis voltages ranging from 0.30 V to 1.60 V depending on the supply voltage. The component is housed in a TSSOP-14 package.

Inverter Gates Feature Summary

• Schmitt trigger inputs provide hysteresis for squaring up slow signals and maximizing noise immunity
• High-speed operation comparable to Bipolar Schottky TTL while maintaining low power dissipation
• Power-down protection on inputs prevents device destruction during supply voltage mismatches
• Outputs tolerate voltages up to 5.5 V, allowing interface between 5 V and 3 V systems

Inverter Gates Applications

• Line receiver applications for receiving slow input signals
• Level conversion for interfacing 3.3 V to 5.0 V systems
• Signal conditioning where noise immunity is required

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'DTG' corresponds to the TSSOP-14 package and lead-free status as defined in the manufacturer's ordering information. Confirm that the requested quantity aligns with the specified shipping units for rail or tape and reel options. Ensure compatibility with the recommended operating conditions regarding supply voltage and temperature ranges before finalizing procurement.

Inverter Gates Selection Notes

Select this component when hex Schmitt inverters are required for high-speed CMOS applications. It is suitable for designs needing robust noise immunity and signal shaping capabilities. Consider the TSSOP-14 package constraints and the 2.0 V to 5.5 V operating range. Verify that the input logic levels match the system requirements, as this variant is compatible with standard CMOS levels.
