TC7SZ17FE,LJ(CT

Overview

The TC7SZ17FE,LJ(CT is a non-inverting buffer manufactured by Toshiba Semiconductor and Storage, belonging to the TC7SZ logic series. It features a single input and output configuration with Schmitt trigger inputs for noise immunity. The device operates on a supply voltage range of 1.65V to 5.5V and utilizes push-pull outputs capable of sourcing and sinking 32mA. It is housed in a compact surface-mount package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Schmitt trigger input action provides improved noise tolerance and signal conditioning
• Wide operating voltage range supports low-voltage digital systems from 1.65V up to 5.5V
• High drive capability allows direct interfacing with loads requiring significant current
• ESD protection structure enhances reliability during handling and operation

Applications

• Signal buffering in portable battery-powered devices
• Clock distribution networks requiring noise filtering
• Level shifting between different voltage domains
• Interface circuits for microcontrollers and memory modules

Procurement Notes

Verify the specific suffix FE against the official Toshiba datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the ordering code includes the correct packaging designation such as cut tape or reel. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when high noise immunity is required due to its Schmitt trigger inputs. The wide voltage range makes it suitable for systems transitioning between 1.8V and 5V standards. Consider the 32mA output drive strength for driving capacitive loads directly. Verify that the SC-70-5 package fits the available PCB space constraints compared to larger alternatives.

Part Context

This part belongs to the TC7SZ family of L-MOS logic devices designed for low-voltage applications. It serves as a single-channel buffer within Toshiba's portfolio of small-signal logic ICs. The series emphasizes low power consumption and high speed while maintaining compatibility with standard CMOS logic levels across various supply voltages.

Replacement Considerations

The NL17SZ17XV5T2 from onsemi is a documented alternative offering similar electrical specifications and pinout compatibility. Verify functional equivalence regarding propagation delay and output current capabilities before substitution.
