74HC245PW,112

Overview

The Nexperia 74HC245PW,112 is an octal bus transceiver with 3-state outputs housed in a TSSOP20 package. It operates within a supply voltage range of 2.0 V to 6.0 V and features non-inverting data transfer between A and B ports controlled by DIR and OE signals. The device complies with JEDEC standards JESD8C and JESD7A, offering high noise immunity and CMOS low power dissipation. Inputs include clamp diodes for interfacing with voltages exceeding VCC.

Feature Summary

• Octal bidirectional bus interface with non-inverting 3-state outputs
• Wide supply voltage range from 2.0 V to 6.0 V
• High noise immunity and CMOS low power dissipation
• Input levels compatible with CMOS logic

Applications

• Mixed 5 V and 3.3 V applications
• Improving current drive and voltage level of signals
• Improving signal integrity for complex layouts

Procurement Notes

Verify the specific ordering suffix '112' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure the selected component matches the required temperature range and package variant (TSSOP20) for your design constraints. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and compliance with current product status definitions.

Selection Notes

Select this component when an 8-bit bidirectional bus interface with 3-state outputs is required. The HC logic family supports a wide voltage range suitable for mixed-voltage systems. Verify that the input voltage levels align with the driving source, as this variant utilizes CMOS input levels rather than TTL levels found in HCT counterparts.

Part Context

This component belongs to the 74HC245 series of octal bus transceivers manufactured by Nexperia. It shares functional similarities with other variants like the 74HCT245 but differs in input logic levels. The PW suffix indicates the TSSOP20 plastic thin shrink small outline package, providing a compact surface-mount solution for PCB layout optimization.

Replacement Considerations

The 74HC245PW,118 is a documented alternative from Nexperia using the same TSSOP20 package and logical functionality. Verify pinout compatibility and electrical characteristics before substitution.
