74LCX07MTCX

Overview

The onsemi 74LCX07MTCX is a low-voltage CMOS hex buffer featuring open-drain outputs and 5V tolerant inputs. It operates within a supply voltage range of 2.0 V to 3.6 V, with a maximum rating of 5.5 V. The device provides symmetrical output impedance with high-level and low-level output currents of 24 mA at 3.0 V. It exhibits a typical propagation delay of 5.2 ns at 3.0 V and maintains a static current of 10 µA. Packaged in a 14-TSSOP format, it supports surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Features 5V tolerant inputs allowing direct interfacing between 3.3V logic systems and 5V signal environments.
• Provides open-drain outputs suitable for wired-OR configurations and level shifting applications.
• Incorporates power-down protection ensuring inputs and outputs remain in a high-impedance state during shutdown.

Applications

• Low-power and high-speed 3.3V digital logic buffering
• Level translation between 3.3V and 5V signal domains
• Wired-OR bus line driving

Procurement Notes

Verify the specific suffix 'X' against the manufacturer's official documentation to confirm packaging details, as standard datasheets may reference tube or tape-and-reel variations without explicit suffix definitions. Ensure the component matches the 14-TSSOP pinout and electrical specifications required for the target circuit design before procurement.

Selection Notes

Select this component when open-drain output capability is required for 3.3V applications interfacing with 5V systems. The 74LCX07MTCX is appropriate for designs needing 5V input tolerance and low quiescent current. Consider the TSSOP-14 package constraints and verify that the open-drain nature aligns with the downstream pull-up requirements of the application.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices manufactured by onsemi. The LCX family is designed to offer performance comparable to older 5V AC/ACT families while consuming significantly less power. The 74LCX07 variant specifically provides hex buffering with open-drain outputs, distinguishing it from standard push-pull buffers in the same series.

Replacement Considerations

Compatible substitutes include the MC74LCX07MTC and MC74LCX07MTDX from onsemi, which share identical logical functions and pinouts. Other manufacturers offering equivalent 74LCX07 devices in TSSOP-14 packages may serve as alternatives if electrical parameters match the original specifications.
