SN75454BDR

Buffers, Drivers, Receivers, Transceivers Overview

The SN75454BDR is a dual high-current peripheral driver manufactured by Texas Instruments, designed for TTL logic systems. It features two non-inverting channels with open-collector outputs capable of sinking up to 300 mA at low levels and sourcing 100 µA at high levels. The device operates within a supply voltage range of 4.75 V to 5.25 V and draws a typical operating current of 56 mA. It is housed in an 8-pin SOIC package and supports surface-mount installation. The component functions as a NOR gate-based peripheral driver with a propagation delay of 35 ns.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'BDR' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before finalizing procurement. Ensure the ordering quantity matches standard reel sizes to avoid cut-tape premiums if applicable.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require moderate speed and high current drive capabilities for TTL-compatible logic. It serves as a suitable replacement for older SN75450 series drivers where higher current capacity is needed. Consider the thermal dissipation characteristics of the SOIC-8 package under continuous load conditions during the selection process.
