74AHC245PW,112

Buffers, Drivers, Receivers, Transceivers Overview

The 74AHC245PW,112 is an octal bus transceiver manufactured by Nexperia. It features non-inverting 3-state outputs and operates within a supply voltage range of 2.0 V to 5.5 V. The device includes output enable (OE) and direction control (DIR) inputs. Propagation delay is typically 8.4 ns at 3.3 V with 15 pF load. Input levels are CMOS compatible. It supports an operating temperature range from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transmission between two 8-bit buses using a single direction control input.
• Features overvoltage tolerant inputs allowing operation in mixed-voltage environments without external level shifters.
• Includes Schmitt-trigger action on all inputs for improved noise immunity and signal conditioning.

• Memory mapping in embedded systems
• Clock drivers and buffered oscillators
• Bus-oriented communications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation carefully, as the datasheet identifies this component under Nexperia rather than NXP USA Inc. Confirm the specific suffix matches the TSSOP-20 package variant. Ensure the order aligns with the current product status defined in the official documentation before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an 8-bit wide bidirectional interface is required with high-speed performance. The AHC logic family offers balanced propagation delays suitable for general-purpose digital applications. Verify that the system voltage falls within the specified 2.0 V to 5.5 V range to ensure proper functionality.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC series of high-speed silicon-gate CMOS logic devices. It serves as a standard solution for connecting microprocessors to peripheral devices or memory blocks. The PW suffix indicates the plastic thin shrink small outline package, which is widely used in surface-mount assembly processes.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT245PW,112 is a functional alternative if TTL-compatible input levels are required instead of CMOS levels. Other variants such as the 74AHC245D offer the same electrical characteristics but utilize a different SO20 package format.
