SN75471P

Buffers, Drivers, Receivers, Transceivers Overview

The SN75471P is a dual peripheral driver manufactured by Texas Instruments in an 8-pin PDIP package. It operates with a supply voltage range of 4.75 V to 5.25 V and supports continuous output currents up to 300 mA, with peak currents reaching 500 mA. The device features TTL-compatible diode-clamped inputs and provides high-voltage outputs capable of withstanding off-state voltages up to 70 V without latch-up. Characterized for operation between 0°C and 70°C, it implements AND logic functions internally connected to NPN output transistors.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and material finish. Confirm that the required operating temperature range aligns with the standard 0°C to 70°C characterization. Ensure input logic levels match the specified TTL-compatible thresholds for reliable switching performance in the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when higher breakdown voltages are required compared to the SN75451B series. Note that switching speeds are slightly slower than the SN75451B but match the limits of the SN75461 series. Verify that the power dissipation requirements fit within the thermal derating curves for the chosen ambient temperature conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN7547x series of dual peripheral drivers, which also includes the SN75472 (NAND) and SN75473 (OR). These devices are functionally interchangeable with the SN75451B and SN75461 series but are optimized for systems requiring higher breakdown voltages. The series utilizes a plastic DIP package with a copper lead frame for improved reliability.
