74LVC2245ADB,112

Overview

The Nexperia 74LVC2245ADB,112 is an octal bus transceiver featuring 30 Ω series termination resistors and 3-state outputs. It operates with a supply voltage range of 1.2 V to 3.6 V and supports overvoltage tolerant inputs up to 5.5 V. The device includes Schmitt-trigger action for noise immunity and IOFF circuitry for partial power-down applications. It complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Operating temperature ranges from -40 °C to +85 °C and -40 °C to +125 °C.

Feature Summary

• Integrated 30 Ω series termination resistors for signal integrity
• IOFF circuitry prevents damaging backflow current during partial power-down
• Schmitt-trigger inputs provide tolerance for slow rise and fall times
• Direct interface capability with TTL logic levels

Applications

• Mixed 3.3 V and 5 V environment translation
• Octal bidirectional bus interfaces
• Partial power-down system designs

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74LVC2245A family includes SO20, TSSOP20, and DHVQFN20 variants. Confirm that the 'ADB' designation aligns with the intended physical footprint and thermal requirements for the target PCB layout. Ensure compliance with relevant RoHS and REACH directives for the final assembly process.

Selection Notes

Select this component when designing systems requiring integrated termination to reduce external component count. It is suitable for applications needing robust ESD protection and compatibility with both 3.3 V and 5 V logic domains. Consider the wide supply voltage range and low-power consumption characteristics for battery-operated or energy-efficient designs.
