74HC245PW/AUJ

Buffers, Drivers, Receivers, Transceivers Overview

The 74HC245PW/AUJ is an octal bus transceiver manufactured by Nexperia, housed in a TSSOP20 package (SOT360-1). It provides bidirectional data transfer between two 8-bit buses with non-inverting 3-state outputs. The device operates within a supply voltage range of 2.0 V to 6.0 V and features direction control via the DIR input and output enablement via the OE input. Inputs include clamp diodes for interfacing with voltages exceeding VCC.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bidirectional bus interface with non-inverting 3-state outputs
• Direction control via DIR input and output isolation via active LOW OE input
• Input clamp diodes allow interfacing to voltages exceeding VCC using current limiting resistors
• Complies with JEDEC standards including JESD7A and ESD protection specifications

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between data buses
• Cascading logic circuits requiring bus isolation
• Systems utilizing CMOS or TTL logic levels

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the AUJ suffix corresponds to the specific tape and reel packaging configuration defined by Nexperia for the 74HC245PW variant. Confirm the component status as a production part rather than a development or obsolete item before finalizing design integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an 8-bit bidirectional interface with 3-state capability is required. Ensure the application voltage falls within the 2.0 V to 6.0 V range. Consider the TSSOP20 package dimensions if board space is constrained compared to standard SO packages.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. It functions as an octal transceiver, distinct from unidirectional buffers or single-channel receivers. The PW designation indicates the Thin Shrink Small Outline Package format.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74HCT245PW serves as a functional replacement if TTL-level inputs are required instead of CMOS-level inputs. Other 74HC245 variants in different packages may be used if pin compatibility and thermal requirements are met.
