TD62308AFG,S,EL

Drivers, Receivers, Transceivers Overview

The TD62308AFG,S,EL is a four-channel low-side sink driver manufactured by Toshiba Semiconductor and Storage. It integrates four NPN Darlington output stages with PNP input stages, designed for direct interfacing with 5V TTL, 5V CMOS, and microprocessor logic. The device supports a maximum output current of 1.5A per channel and withstands a minimum sustaining voltage of 50V. Key electrical parameters include an operating supply voltage range of 4.5V to 5.5V, a typical on-resistance of 370 milliohms, and a quiescent supply current of 200uA. It operates within a temperature range of -40°C to +85°C and is housed in a 16-pin HSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates four independent high-current Darlington sink channels for driving inductive loads such as relays and motors.
• Features internal clamp diodes to protect against voltage spikes generated by inductive load switching.
• Provides direct compatibility with standard 5V logic families including TTL and CMOS without additional level shifting.

Drivers, Receivers, Transceivers Applications

• Stepping motor drivers
• Relay control circuits
• Hammer and lamp drivers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'S' against official Toshiba documentation to confirm pinout or thermal pad variations. Ensure the ordering code matches the required tape-and-reel quantity. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and availability before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a compact solution for driving multiple low-side inductive loads from 5V logic is required. The 50V breakdown voltage accommodates common automotive and industrial relay voltages. Consider the HSOP package constraints for thermal management if continuous high-current operation near the 1.5A limit is expected.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TD62308 family of Darlington arrays. While similar to the non-inverting TD62308AP/AF, verify if the 'S' suffix denotes a specific variant or packaging difference compared to the standard AFG version. The family is widely used in embedded systems requiring robust current sinking capabilities from small form-factor packages.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify pin-to-pin compatibility with other Toshiba Darlington arrays like the TD62083 series only after confirming functional equivalence in the specific application circuit.
