MC74VHC1G50P5T5G-L22088

Overview

The MC74VHC1G50P5T5G is a single-channel, non-inverting buffer from the 74VHC series. It operates within a supply voltage range of 2.0 V to 5.5 V and features push-pull outputs capable of sourcing and sinking 8 mA at 3.0 V. The device utilizes advanced high-speed CMOS technology with propagation delays as low as 3.5 ns at 5 V. It includes over-voltage tolerant inputs and outputs up to 5.5 V, supporting IOFF for partial power-down protection. The component is housed in an SOT-953 package.

Feature Summary

• Advanced high-speed CMOS technology designed for compact footprint applications
• Input and output structures provide over-voltage tolerance up to 5.5 V regardless of supply voltage
• IOFF feature supports partial power-down protection to prevent excessive current draw
• Push-pull output configuration ensures robust drive capability across the operating voltage range

Applications

• Interfacing 5 V circuits to 3 V circuits
• Portable equipment requiring low power consumption
• Battery-powered systems utilizing partial power-down modes

Procurement Notes

Verify the specific ordering suffix P5T5G corresponds to the SOT-953 package and tape & reel shipping configuration. Confirm that the device code matches the required logic family variant (CMOS level thresholds). Ensure compliance with RoHS and Pb-Free requirements as specified in the datasheet documentation before finalizing procurement orders.

Selection Notes

Select this component when a single-channel non-inverting buffer is required in a small SOT-953 package. It is suitable for designs needing 8 mA drive strength and operation between 2.0 V and 5.5 V. Consider the MC74VHC1GT50 if TTL level input thresholds are preferred instead of CMOS levels. Verify thermal resistance and power dissipation limits for the specific PCB layout.

Part Context

This part belongs to the MC74VHC1G50/MC74VHC1GT50 family of single-gate buffers. The 'P5' suffix indicates the SOT-953 package type, while 'T5G' denotes tape and reel packaging with lead-free composition. The base logic function remains consistent across package variations within the 74VHC series.

FAQ

What is the difference between MC74VHC1G50 and MC74VHC1GT50?

The MC74VHC1G50 has CMOS level input thresholds, whereas the MC74VHC1GT50 has TTL level input thresholds. Both share identical output characteristics and package options.

How does the IOFF feature benefit the circuit?

The IOFF feature provides partial power-down protection by limiting leakage current when the device is powered down but still connected to live buses, preventing damage during hot insertion or battery backup scenarios.
