74AC14MTCX

Overview

The onsemi 74AC14MTCX is a hex inverter integrated circuit belonging to the AC logic series. It features six Schmitt trigger inputs and operates within a supply voltage range of 2 V to 6 V. The device provides high-level output currents up to -24 mA and low-level output currents up to 24 mA. It exhibits a maximum propagation delay of 13.5 ns at a 50 pF load. The component is housed in a TSSOP-14 package with dimensions of 5 mm x 4.4 mm x 0.9 mm and supports surface mount installation across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates six independent inverters with Schmitt trigger input thresholds for noise immunity
• Delivers symmetrical drive capabilities with 24 mA source and sink current capacity
• Operates efficiently across a wide 2 V to 6 V power supply range

Applications

• Signal conditioning and waveform shaping
• Clock signal generation and buffering
• Oscillator circuits requiring hysteresis

Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives and check for any regional compliance requirements before procurement. Confirm that the supplier provides valid traceability documentation for the onsemi manufacturing lot.

Selection Notes

Select this component when designing CMOS logic circuits requiring precise switching thresholds and noise rejection. The AC logic family offers higher speed performance compared to standard HC series devices while maintaining compatible pinouts. Verify that the system's voltage levels align with the 2 V to 6 V operational range and that thermal constraints fit the TSSOP-14 footprint.

Part Context

This part belongs to the 74AC logic family, which represents advanced CMOS technology offering faster switching speeds than earlier NMOS or standard CMOS variants. The '14' designation specifically indicates a hex inverter configuration, distinguishing it from buffers or gates within the same series. The MTCX suffix typically denotes the TSSOP-14 surface-mount package and reel packaging format.

Replacement Considerations

Cross-reference with other manufacturers' 74AC14 equivalents such as those from NXP or Texas Instruments. Verify pinout compatibility and electrical parameter alignment, particularly propagation delay and output current ratings, before substituting.
