74LVC4245ABQ,118

Translators, Level Shifters Overview

The Nexperia 74LVC4245ABQ,118 is an octal dual supply translating transceiver featuring 3-state bus compatible outputs in both send and receive directions. It interfaces between a 3 V and 5 V bus in mixed supply environments. The device includes output enable (OE) and direction control (DIR) inputs. Supply voltage ranges are 1.5 V to 3.6 V for the 3 V bus (VCC(B)) and 1.5 V to 5.5 V for the 5 V bus (VCCA). Propagation delays range from 1.0 ns to 8.5 ns depending on conditions. Operating temperature spans -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Provides bi-directional data translation between different voltage domains
• Features Schmitt-trigger inputs for tolerance of slow rise and fall times
• Includes high-impedance state when either supply voltage is zero

Translators, Level Shifters Applications

• Interfacing between 3 V and 5 V logic buses
• Mixed 3 V and 5 V supply environments
• Systems requiring bi-directional level shifting

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix ABQ corresponds to the DHVQFN24 package (SOT815-1) as defined in the official Nexperia documentation. Confirm that the component meets the required thermal and electrical specifications for the intended operating temperature range of -40 °C to +125 °C before finalizing procurement decisions.

Translators, Level Shifters Selection Notes

Select this component when designing systems that require connecting 8-bit buses operating at different voltage levels, specifically between 1.5 V–3.6 V and 1.5 V–5.5 V domains. Ensure the application utilizes the DHVQFN24 package format and requires the specified propagation delay characteristics and ESD protection levels provided by the LVC logic family.

Translators, Level Shifters Part Context

This part belongs to the 74LVC4245A series of octal dual supply translating transceivers manufactured by Nexperia. It is designed for low-power CMOS applications and offers compatibility with TTL logic levels at 3.3 V. The series supports multiple package options including SO24, TSSOP24, and DHVQFN24, catering to various PCB space and thermal requirements.

Translators, Level Shifters Replacement Considerations

Direct substitutes include other variants within the 74LVC4245A family such as 74LVC4245AD (SO24) or 74LVC4245APW (TSSOP24), provided the package footprint difference is accommodated. Verify pinout compatibility and electrical parameters match the design requirements.
