74LVC4245APW,112

Translators, Level Shifters Overview

The Nexperia 74LVC4245APW,112 is an octal dual supply translating transceiver with 3-state outputs. It interfaces between a 3 V bus (VCC(B): 1.5 V to 3.6 V) and a 5 V bus (VCC(A): 1.5 V to 5.5 V). The device features Schmitt-trigger inputs for slow signal tolerance and direction control via DIR and OE pins. Propagation delays range from 1.0 ns to 8.5 ns depending on voltage and temperature. It operates from -40 °C to +125 °C in a TSSOP24 package.

Translators, Level Shifters Feature Summary

• Dual supply architecture enabling translation between 1.5 V to 3.6 V and 1.5 V to 5.5 V domains
• Schmitt-trigger action at all inputs provides tolerance for slower rise and fall times
• High-impedance OFF-state isolates buses when output enable is inactive or supplies are zero

Translators, Level Shifters Applications

• Interfacing mixed 3 V and 5 V logic systems
• Bus translation in embedded environments requiring wide temperature operation
• Applications needing high-impedance isolation during suspend modes

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP24 package variant. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure supply voltage constraints are met, specifically that VCCA remains greater than or equal to VCCB during normal operation. Check for any automotive qualification requirements if the application demands AEC-Q100 compliance, as this standard version may not be qualified.

Translators, Level Shifters Selection Notes

Select this component when bidirectional data transfer between disparate voltage levels is required. The TSSOP24 package offers a compact surface-mount solution for space-constrained designs. Consider the propagation delay specifications relative to system clock speeds. Verify input voltage compatibility with driving sources, noting the overvoltage tolerant control inputs up to 5.5 V.

Translators, Level Shifters Part Context

This part belongs to the 74LVC4245A family of octal bus transceivers. Other variants include the SO24 package (74LVC4245AD) and DHVQFN24 package (74LVC4245ABQ). All share identical electrical characteristics but differ in physical footprint and thermal properties. The family supports CMOS low-power consumption and complies with JEDEC standards for I/O structures.

Translators, Level Shifters Replacement Considerations

Direct substitutes within the same package include 74LVC4245AD,112 (SO24) and 74LVC4245ABQ,112 (DHVQFN24), provided pinout compatibility and thermal management requirements are addressed. Cross-family replacements require verification of voltage levels and pin configurations.
