SN75454BPG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN75454BPG4 is a dual high-current peripheral driver manufactured by Texas Instruments. It features two independent drivers with open-collector outputs, designed for TTL logic systems. The device operates within a supply voltage range of 4.75V to 5.25V and supports peak output currents up to 0.5A. It is housed in an 8-pin PDIP package and functions as a NOR gate-based peripheral driver.

• TTL-compatible inputs with internal diode clamping
• Designed to prevent latch-up during high current conduction

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed logic buffering
• Relay driving circuits
• Lamp and MOS driver applications
• Memory driver interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and manufacturing revisions against the official Texas Instruments datasheet. Confirm the PDIP-8 package dimensions match the design requirements. Ensure the operating temperature range aligns with the system environment before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing TTL logic with high-current loads requiring open-collector sinking capability. It serves as a functional replacement for older SN75450 series devices. Consider the 8-pin DIP package constraint for through-hole mounting designs requiring robust peripheral drive capabilities.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN7545x family of peripheral drivers from Texas Instruments. It is functionally interchangeable with previous SN75450 and SN75450A series devices while offering improved latch-up immunity. The G4 suffix denotes environmental compliance modifications.
